I have them on one of my 20 or so Revs (the 64 II one) and they look good on that, but they do limit my playing. As that bass has flatwounds, the fact that I cannot dampen strings well anymore isn't quite as crucial, but my playing is still affected by the ashtrays. More so than by the treble pup cover of a Ric which I see as disciplining me to play closer to the bridge than I normally would. Besides, that Ric pup cavity looks just awful. The TBird, otoh, has nothing to hide.
But practicality aside those remakes are nice.
