I have a number of WSS period hussars left after building up armies (most of a pack). I'm thinking what to use them as...what would they be ok as?

Options are as;

7 Years' War hussars

Mix them in as Polish cossacks (Lisowskis or similar) with the Polish unarmoured cavalry figures

Ukrainian cossacks

Any opinions on the acceptability for any of the options, or any other suggestions for use?

Thanks

If you are interested in the wars with the Ottomans in 17th/ early 18th cent., perhaps Transylvanians? Or simply Hungarians? Maybe its possible to mix them with others for a Tatar force. 

I was thinking more the Northern Wars; Poland, Muscovy, Sweden and Cossacks rather than the Ottoman wars (although I could be tempted...). But Transylvanians, Vlachs and Tatars are a good idea,Polish army. Thanks.
