Should work fine but it could be a close fit.
On my 2010 Trail wheels I went narrow wall spec, I use this one with my 1/2" breaker bar.

Also, a 13/16" 6 pt deep spark plug socket has worked well for me and fits my 3/8" torque wrench. It's actually slightly smaller than 21mm so it's nice and snug (.8125 vs. 0.8268). I've got one that has both measurements inscribed on it.
IIRC I've heard most lug nuts are purposely sized in SAE equivalents: 17, 19, 21, & 23 MM or 11/16, 3/4, 13/16, 7/8.
