Thank you! 
Yes seems it is possble, but will need much more work from my side.
Lets say to prepare one collection will take a 4-5 workdays.
I will need go and fix every animation. And in case of archer it may take even more time.
So I don’t advise you to purchase Unity pack. I didn’t decide yet to go on this war.
And in any case I will prepare some characters first.
