i was thinling about putting 23's on mine but after seeing what modifications you have to do, one little inch wont make a difference, if your going to do it at least go with a 24", but you'll have to have a super duper low profile tire.
I think you will at least have to shave down the nut for the upper ball joint for 23's. You will have a rubberband for a tire. So I wouldn't recommend it for a daily driver, unless you can stand the ride quality and afford new rims when the potholes eat them up.
I just had a flat with my low profiles on 20's and barley made out with saving my rim. I've decided to go with a semi low profile due to my daily driving. The quality of the ride will be better and I won't have to worry so much about loosing a rim if this happens again.
I can't imagine 23's as just going with a taller walled tire on 20's is going to put me close to the bolt. Rubber bands would describe the tire's well and the risk taken may not be worth it. 20's and 22's look perfect on the Mags in my opinion. Then you still have room to lower if wanted.
