Can the Zvezda Russian dragoons not stand in for Prussian cuirassier?

Yes except Zvezda have only ever made 2 mini set of the Russian Dragoons 3x troopers and 3x command at £4.50 per box or £1.50 per figure, Waterloo 1815 did make Prussian Cuirassiers in metal £23.60 for 6 figures or £3.93 per figure.

I think the best bet would be to ask Strelets to release their Russian Dragoons from the Borodino big box separately.

I would like to add my support for Strelets to make Nap Prussian Landwehr Cavalry using their latest Napoleonic sculptors.
