Need For Speed :: San Andreas

Hello. Today I want to present you my idea.
It's based on nfs (2015). I think it's possible [but crew must edit cars (windows template) or maybe some shader].
Stickers on windows.
How Cool this sound?
If you want to make rally car, you do. You will be put flag and your name on window! etc...
I think it's just a feature, but it's good.

What do you think?
Example movie:

Yes, edit 40+ cars, good luck.. Also this would be HUGE edit, and do it for each car separately. We are not that mad to do it, at least now...
About possibility? Tbh I don't think is it possible to make it good looking and working because of GTA engine alpha rendering which is very glitchy and even best shader can't do abolutely anything.

gta sa engine is kinda old for this kinda things don't ya think?

The way I'd do it is the same that was done to the decals. I'd up a mesh above the windows and make the vinyls move in that.
It does mean edit all the cars one by one, though... No way outta there.
