The EosR mount to sensor distance is 20mm( Source: Canon) , however the FSQ flattener requires 56.2mm (Source: Takahashi America)
which.....oddly enough... is what you will get when you attach the EOS to EOSr lens adapter.

In short, use a wide-mouth EOS T-adapter (there are many available) with the Canon EOS to EOSr adapter and it should all work out nicely.
