I couldn't help noticing that all your config entries list the "ui_type = C-47R Skytrain" except the Bush entry that calls it "ui_type = C-47 Skytrain"
That won't make it not show up, but it may not appear in the selection list grouped with the other varients. Try changing the ui_type to "C-47R Skytrain" and see if that makes it easier to find.
I've installed lots of v2 paints on the v3 and they all worked ok.
