My question is would this work with the R8? But thinking the screen wouldn't pivot with that solid shape L
Do you have an R8?
I suspect their answer would be yes, it does. But you'd have to use it with the upright bracket spaced away from the body.
I picked up a used RRS L-bracket for the EOS RP, and it works perfectly on the R8 (well, it works as intended, when the upright part of the modular bracket is attached, the screen flips out into the gap but that does restrict the positioning somewhat – I have not found it to be a problem in practice).
