Hello!
Each pike formation is normally covered by musketeers on the edges. Also a few irregular infantrymen (mercenaries/volunteers/armed peasants) on the other side come into play.
Here the first batch:

The usual conversions are made:
Cut off the base / Removing all flash and undercuts / Some head swaps (musketeers normally wore hats) / Changing position of arms and legs / Cut off some feathers on the hats / Making a sash out of aluminium foil and some putty / Adapting the collar with putty / Exchange of swords against sabres / Creating a headgear with putty / Exchange of drumsticks with nails / Pistols made of nails and putty / Cutting off a flag / Some minor changes ...

The painting of the Swedish musketeers is much the same as for the pikemen, the Polish irregular musketeers have no uniform and can be completely freely painted:

Some more complicated conversions now in detail:

Drummer (left): Drumsticks replaced with N-gauge nails for railways / Collar adapted / Arms cut off at shoulder and elbow and glued together in different positions / one leg only bent the other completely cut off and glued in a different position / All gaps filled with putty
Officer (center): Flag cut off / Sash out of aluminium foil and a little putty / Hat feathers taken from another figure / Pistol made of N-gauge nail with some putty / Lower legs cut off and replaced with that of the right figure, as they were a little too short, two nails and putty made them longer / All gaps filled with putty
Musketeer (right): Hat cut off and another headgear made of putty / Bag cut off and glued to the backside, carrying belt also cut off / Sword replaced with a sabre from the hussars / Lower legs replaced with that of the center figure / One upper leg completely cut off and glued on in another position / All gaps filled with putty
Conversions are always a fragile work - the more complicated the more fragile, sometimes hard to paint without damaging the figures.
For the first time I tried to simulate smoke of a firing musket:

The smoke was made by some filling material from an old scrapped sofa and a little liquid plastic glue.
The figures are put in place on the diorama to see the actual effect and I see that there is a second batch necessary ...
