jjames2b- Here's what 650C wheels can get you. I changed the drop, ST length, chainstay length, tube diameters to ones that make more sense with a bike this small. Note the resulting straddle height, HT length, DT/ST angle (59.1*), DT/HT angle (61.1*), toe overlap (now 27mm better then before) changes.

I have no idea as to your seat set back, seat/bar distance or drop, crank arm length. But you should see the much greater range of adaptability and fit possibilities the 650C wheels get you. Of course this means a different fork. The one that i patterned the specs after is a Profile BRS (1" steerer Al and carbon mix, probably no longer available)

I'd be happy to push through more design specs for you after you ponder all this. At worst it would take a day or so if I'm on the shop schedule that day. I can also work directly with you and we can bypass this forum. Andy.
