Stock or custom?

[caducosity]

I've had a Kickr Bike for about a year-and-a-half and I started with a solid professional fitting and adjusted and adjusted (and adjusted) from there, until now I can ride a couple of hours on the trainer with no pain or numbness anywhere. It's great.

Now I'd like to get a bike that matches this setup (I have an IF Planet X that I bought through this forum about 15 years ago that just doesn't work for my older body), and I think I might have adjusted my way out of any stock options, but I'm not certain.

The Hx (BB to center of bar at stem) is 485. The Hy is 729. The drop from the top of the (ISM) saddle to the middle of the bar is -36mm. And the setback (again, keeping in mind that this is an ISM saddle) is 190(!). (My inseam is 843mm, I'm 6 feet tall, and have long arms).

Assuming that these are the dimensions and I don't want to adjust them, are there any stock bikes that might work? I've played around with a bunch of endurance frame numbers, but keep coming up short on the stack. Do I have to go custom?
