I certainly would be very interested in these, Barry.
Such a set would add the "petit guerre" aspect of the era as well as the variants you mention, and allow some of the excellent variety of miniatures from Warfare, Ebor, etc to be used to advantage.
So I could use a grenadier company to take a bridge or outwork, so "justifying" rather more than 2 figures of Nick's excellent Brandenberg Bayreuth grenadiers that are required for a BLB battalion. Nick, that would justify grenadier officers, too!
This would also allow for more "entertaining" grenade rules too!!
And then, there are the flags - as such units would represent companies....! Stuart, Iain!
The NCO and musician figures would also have a roll, as well as officers. Then there are the baggage handlers, the pioneers, coaches & carts, tavern wenches....!!
Perhaps, I could stretch to some Jacobites as well, or Spanish, or Turks even!
Oh yes! Bring them on.
Cheers, Rohan.
