My view is that if you need to push your saddle so far back, do so, it's where your butt wants to be given the riding style. If you can't achieve that position with a normal or at least available seatppost, the seat tube angle needs to be numerically lower - a custom frame perhaps.
After that your desired reach is based on your upper body riding position, and selecting it is much more art than science, thought you can use geometry once you know your desired body posiiton and dimensions. Other considerations include head tube angle and front wheel position, for desired steering and clearances (tight for racing or looser for a tourer or rando-type bike). Then you can set chainstay length to establish weight distribution. That's how you won't have a front wheel that's too light. BTW, have you weighed the bike wheel by wheel with you on board? Then you'll know how far the bike deviates from the "normal" 55% rear 45% front with you on it. Or if you can go through all this as an intellectual, non-frame building exercise, you might be able to find the frame parameters that fit your needs. Then you can just shop for a suitable existing frame. But there's another possibility: your positioning is not best for you when you slam that saddle, and a more basic adjustment and re-acclimation is needed. Yet a third, is to speak to Richard Sachs or another of the "greats," and see if you can pay for a custom frame design. Then shop your desired dimensions to a fabricator who is affordable and with better response time.
