I realize this is kind of an odd request but I play a lot of objectives with my friends and we all use common combinatoona of is of cards. While we’ve been proxying cards I’m interested in making a dual upgrade Integrated Astromech and Flight Assist Astromech card like the R2/IA one from the store kits, among others:

Does anyone have a template for a program like Strage Eons that I can easily make some custom dual upgrades?

I haven't seen any around, but I'm probably not the person to ask.

Although seeing that you have a picture of what you're trying to recreate, you might be able to do something similar with some creative Photoshop-Fu.
