I must admit that I have never been fond of the Marauder. Perhaps it was the steep heat curve or the lack-luster armor arrangement (and amount!). Though, to be honest, the lines of the 'Mech and its general appearance definitely screamed BATTLETECH!
Still, I have found myself using other 'Mechs most often than this one. But I will give the Marauder my best attention and offer to you a few varieties that you may (or may not) find interesting and useful. So, I hope ya'll enjoy my attempt here.
MAD-4D Marauder
As the AFFS (and AFFC) began to overhaul, redesign, and retrofit their BattleMechs to utilize recovered Star League technology, one of the premier candidates was the MAD-3R Marauder. While House Davion already had a fine variant in the MAD-3D, First Prince Hanse Davion wanted to see a new version that stayed more "true" to the original with an advanced autocannon.
General Motors of Kathil responded with the new MAD-4D variant. The design team at GM retained the two Magna Mk II Medium Lasers (right arm, left arm) along with the Magna Hellstar PPC in the left arm. The right arm Hellstar was replaced with a newly developed Magna Firestar Extended-Range PPC. This use of a mixture of standard and ER PPCs was done to minimize the heat spike generated by the new 'Mech.
The older GM Whirlwind Autocannon/5 was replaced with a Defiance Disintegrator LB-10X Autocannon imported from the factories on Hesperus II in the Lyran Commonwealth. Fed by two tons of ammunition (and normally loaded with a mixture of cluster and slug), this weapon matched the range of the GM Whirlwind (and Hellstar PPC), but provided an increase and damage (and flexibility) for minimal heat cost.
Armor protection was increased by the use of 12.5 tons of Ferro-Fibrous armor plating, giving the new MAD-4D excellent protection (especially improved were the protection on the legs and side torsos). To find the mass necessary for these improvements, GM replaced the internal skeletal structure of the 'Mech with an Endo-Steel II frame.
Finally, the design team removed the standard heat sinks and instead fitted the design with thirteen Double-Strength Freezers.
While these are not enough to fully dissipate the heat generated by this 'Mech, it is roughly comparable to the excess overheat production of the MAD-3R and allows for the use of the ER PPC, PPC, and LB-10X autocannon at medium and long range for minimal overheat production. In close, the MechWarrior can use the ER PPC, LB-10X, and both Medium Lasers and remain safely within the green zone of the heat gauge.
The Vlar 300 fusion engine was retained, which meant the new Marauder would see no increase in speed; which greatly affected how the war-machine was deployed after contact was made with the Clans. However, with a standard engine, the MAD-4D remains (relatively) inexpensive (for a heavy 'Mech, at least) and far more survivable on the field of battle than a 'Mech outfited with an Extra-Light engine.
Approved for full-scale production, the MAD-4D was intended to be built at both GM of Kathil and Independence Weaponry on Quentin, but the loss of that facility to House Kurita curtailed plans to build this 'Mech there. Fortunately, when Quentin fell to the Dragon, the factory had not yet received detailed schematics of the MAD-4D and this 'Mech remains in exclusive production for the Federated Suns and Federated Commonwealth.

MAD-4S Marauder
House Steiner received the plans and schematics for the MAD-4D Marauder in return for their providing the newly developed Defiance Disintegrator LB-10X Autocannon. However, the Lyrans were not quite pleased with the design, feeling that it could be iimproved. Defiance Industries of Hesperus II therefore redesigned the MAD-4D into the MAD-4S.
The Endo-Steel II internal structure was removed and replaced with the original GM Marauder chassis, although both of the Magna Mk II Medium Lasers (right arm and left arm). Both the PPC and ER PPC were removed and replaced with a pair of Defiance 1001 Extended-Range PPCs and the Double-Strength Heat sinks increased by three (to a total of sixteen).
The Defiance Disintegrator Autocannon, ammunition, and CASE were then removed and a massive Poland Main Model A Gauss Rifle installed (along with two tons of ammunition).
To accomodate this weapon system, the design team replaced the original Vlar 300 standard fusion engine with an Extra-Light fusion, which had the side effect of greatly increasing the cost of acquisition. To compensate (somewhat) for the increased vulnerability on the battlefield (due to the increased bulk of the XL engine), the design team at Defiance increased the Ferro-Fibrous armor plating to 13.0 tons, giving the MAD-4S Marauder protection equal to that of an Orion
Although still not able to fire all of its weaponry without generating overheat, the increased range of the ER PPCs and Gauss Rifle (and greatly increased damage potential of the Gauss Rifle) caused many officers of the LCAF to salivate in anticipation. Despite the cost increase, the MAD-4S was rapidly approved for full scale production and serves side-by-side with the MAD-4D in Federated Commonwealth units.
