The biggest question would be how to convert Piloting/Gunnery to the tabletop game were that necessary. Of course it's necessary: really important battles should use BT to play out, not some roleplaying system. I thought for a bit, and decided that the D6 system would be the best to use, not because it's the best system (it's pretty good though), but because the learning curve is essentially nil and conversions between the board game and the rp-system would be trivial. Take the Star Wars rpg, change a few skill names, create a couple templates, done. To determine the relevant mech skills if playing out a battle:
|Skill Level||Battletech Equivalent|
Most competent starting mechwarriors would have 4D or 5D in their relevant skills to start, which would put them in the 5/4 range in BT. Which is exactly where they should be. Yes, it's really this simple. When those battles did come up, they could be played out relatively quickly in MegaMek. Coupled with the ease and speed of D6, this makes the whole idea of a MW/BT rpg viable for someone who isn't a 14 year old kid with infinite amount of time over a summer vacation.
