If they include IBIS (as they likely would with a true R7) that would add a certain amount of extra bulk. Not sure how much though.for round numbers, say a half inch taller and wider to account for the increased diameter of the RF mount vs. EF-m mount. That's assuming the screen, EVF, battery, etc stay the same as the comparison body.
I'm not sure those wanting an R7 would want it as small as possible, because they will likely want to mount some pretty big lenses. Now, in terms of (possible) future replacements for the M series, that's where the smaller bodies would have to come into their own.
