Not exactly on point, but it must be noted that
we crossed the bump fairly effortlessly on 4 6" mecanum wheels
The real (heavier) robot took a little extra effort and the wood-metal bump difference was a non-issue.
The wheel modules had built-in deflector plates at 45 degrees and the whole orange modules were made from either 1/8" or .09 aluminum (I forget). We damaged one module when we hit the bump extra fast one time, but it was a quick swap to the spare.
The rest of the modules had very little warp in the deflectors post-season, though some lost some powder coat.
I guess my point is that with careful design considerations, the nature of the wheels doesn't have to matter.
