[ssbashworld]

I think so, am curious as to if translating the style like they did g&w would be too off putting though (hopefully not since its such a big part of the appeal)

[Northsouthmap]

Yes, with using different Emblems

Max (Life is Strange)

 

[Perkilator]

Yes, with using different Emblems
