I bought miniatures for leaders according instruction (attached) - and play with them is great.

Do we find an idea for figures of the new leaders?

Except Jabba, for him it's simple

There are Shadow Trooper mini which work well enough for Krennic's Finest.

Motti never got a mini, so a generic Officer will probably have to do. Krennic you could re-paint a Thrawn mini, I expect that'd be the easiest route. Cassian and Jyn could also be some generic rebel miniatures, there were a number of them that could work without too much of an issue.

Saw and Chirrut are going to be the hardest, because they have pretty unique styles. Probably finding some generics and doing some heavy repaints...

I dont know if they are the same size but these could work....

great idea.

Infortunatelly, in comments they said tall of figures is about 3.5".

It looks like they doublesized compare to old set.

Anyone try the Micromachines? Don't know what their scale is.
