If he can just be convinced to give up ambitions of conquest he might have a grand old time as a 'Master of the Wyld Hunt' sort of figure smashing and blasting across Europa smiting and feasting, and it's not like Europa is liable to run out of 'things needing some well-justified smiting' anytime soon (and if it somehow did, Martellus could run off with the Dreen and hunt across the boundaries of time and space itself).
