Yes in my sleep actually. I get ideas from dreams. Usually I commit a problem to memory and chew on it during the night and eventually some answer appears about midday.
I think it could work for a Napoleonic game too. fewer units and greater differences between them.
Artillery could cost 3 per strength hit @ 1-3, and roll 3 dice
Cavalry could cost 2 per hit @ 1-2 and roll 2 dice
Infantry could cost 1 per hit @ 1, and roll one die
Cavalry allows defender retreats, and on the first round they get three dice @1-2
Infantry can square, which reduces attacking Cavalry to hit @1 at 1:1 basis
Artillery can bombard, which means against squares at 1:1 basis a bonus
against line infantry with no cavalry support they get a first round bonus.
all one round of combat
Generals could boost movement +1 or ??
