I was thinking that the Sharpe's series of books would work well as a setting using TROS as the basis as the books often feature the theme of: what is worth risking your life for?

Any thoughts on the matter?

The Riddle of Black Powder

Should be good (ponders what character concept, philosophy and SA’s Sharpe would have).

The lethality of Napoleonic warfare should suit RoS.
I suppose rather than playing as Sharpe you would create a similar group of men as Sharpe and his chosen men and let them get into the same sort of exploits.

Hmm, Richard Sharp will march again.
