I suppose that in an ideal world these figures would be in cross-belts but with no back-pack, and be in quite rigid poses. I don't think any 1/72 Napoleonic set fits the bill in its entirety, although there are figures in many sets that would work.
How about the new Strelets Russian infantry shoulder arms set? They have back-packs, but would paint up nicely as ranks of Nutcracker warriors?
The Nutcracker soldiers have a look of early Vicorian ,rather like the soldier onthe Quality street (chocolates) packaging , so Crimean war figures may be closer , or metal Indian mutiny ,first Afghan war.
