Regarding Sharp Practice for the Mutiny, there's an article and scenario for this in one of the TFL Specials. There's also a more comprehensive supplement for the period in draft/play test called "War Without Mercy" which may see the light of day once SP v2 is released sometime in 2016.
The new Osprey "Men Who Would Be Kings" colonial rules (again, September 2016 release) will also work well - the core rules feature quite small forces (40-50 British figures v. 90-100 Mutineers would be typical) but could be readily up scaled for larger games.
So..plenty of time to get those figures painted before you play!
