Another payment way in Supporter?

Hello,

I am using Supporter but it's not enough for me (as user from Georgia) Amazon or PayPal payment systems because - Amazon paying system is very unpopular in Georgia and PayPal is planned to add Georgia in it's list at the end of this year, so it isn't available for us yet.

So, I'd like to insert another, Georgian e-payment system, which supports everything what is required. I just wonder if there will be any trouble from "Supporter" while installing new payment system?
