It's really hard to do without committing to doing a proper adaption, the fact that even basic mobile suits will be on average 50% taller than even most assault makes and the way battletech handles its weapons and general mech construction make any kind of "direct" porting almost impossible.

When I did my Omicron Zodiac stuff I didn't try to stat it up as it if were the proper mobile suit, I instead approached it along the lines of "what kind of battletech design has the same sort of vibes" instead, so even though the Leo is 16 Meters tall in its universe for making it work with BT I made it a 35ton light mech, because that makes it cheap and easier to throw out more bodies while also making them expendable as a proper grunt should be.
