True. I'm not sure how a switch to drops without use of a much shorter stem can make the bike feel smaller.
I got the impression that smaller feel came from a switch to slicks.
The rim size change the OP's interested in can change BB height, standover and steering geo. It will do nothing for major fit realationships of BB-saddle-bars
