Is there a way to make a skin template from a NON-DEFAULT skin

Hello, does anyone know if it’s possible to make a template starting off by the non-default skin of a jet? Thing is I really like the skin itself and I just want to make a template for it to be able to add a custom burner to it, any suggestions? (Like some way of downloading the skin file and make it a custom skin)

I’ll leave an example of the skin I want to make as a template down here:
