I believe Pyyer's extension is designed to work off of the base track, not my 2023 raceday addon. So in theory you can have both installed and they come up as different layouts in the track's list of layouts. Then you just choose the one you want to drive. The skins, if you choose to use any of them, should work for any layout. Hope that answers your question. If not, shoot me a PM or ask in the discussion thread.
