Personally I've done the following
95th rifles 36 figures on 6 bases of 6, and 36 figures in ones and two's
1/52nd and 1/43rd both big battalions with 48 figures , 8 bases of 6, and 24 figures skirmishing in ones and two's
French Light battalions 36 figures, 6 bases of 6, and 18 figures skirmishing in ones and two's (the carabinier and voltigeur companies and one centre company.
I include a couple of officers on the skirmish line then you can also use them for skirmish games, which was all i could do initially whilst starting to build up my forces...
