I suppose with stem lengths and different types of bars you can do some experimenting. Thinking it through more fully, I'm going to take back what I said about the pedal to seat length needing to be different because of your sitting position. Seems like you'd want it about the same as it's not like your femurs change length just because you're not leaning forward. Still think that tall bike with a shorter top tube seems like a good first try. Post here what you find out, if you please.
