I'd suggest you'll find the same benefits in size reduction from P226 to P229 as you would from a G31 to G32.
Depends on your metric. If going by overall height the 226/229 are much closer than the 19/17. So much so that there's functionally no difference between the two for concealment on me.
The .40 framed 229 (and 9mm 229-1) is also wider than the 226, marginally but enough that I much prefer the thinner 226 (or older 229/228) frame for comfort. It's possible the slightly thinner frame of the 226 might conceal better for some folks as well.
