linerkiller, iambecomelife, I
probably discovered how to add skins to existing ships in a none overwriting way. I can't test it atm to see if it works but if you want to take a look at the example mod i made to better understand how it is (hopefully) done, then here it is:

If this would work it would make ship-skin addons completely non-conflicting with
any other mod.
I hope it DOES work...
