Happymcclap we do exactly the same. We even use some FoW bases for ease of movement in bigger games. The figs like this work really well for CofC if you want a more in depth tactical ww2 game vs the lighter BA rules.
The only thing which can be done (especially in large games) is to doubling max range of all weapons. Short/effective range stays as is, but the max would be double that listed. That would not make much of a difference in normal games but in very large multi-player games it can.
