OK, So I'm like a year late.
But, here is the idea and first proof of concept cover.
Was awful time consuming to make actually. I would say about 2 hours for the one cover. I haven't removed the backing on the rear lexan yet as I just want to see if it will work as a proof of concept before I do a complete version. Will be driving around for a few days to make sure it's not going to cause issues, then will probably re-do and touch up a couple things and make a set for all 4 wheels. I was thinking too: This should be possible to do by drilling directly into the wheel face and tapping it, but would be a permanent change. It would certainly be easier to line everything up then, also plan to change out the bolts with possibly a allen head instead of the 10mm bolt but thats minor stuff.
