I went down that road once too.
Had my 5D and I was using mostly m42 lenses on it. Was thinking of getting a screen optimized for faster lenses and a split circle in the middle but then I realized that the image on my stock screen was WAY OFF compared to what I was getting at the end. I was either going to shim the screen somehow or find another way.
The best solution I came up with was using adapters with EMF chips on each lens. You can calibrate those lenses for AF microadjustment (Also focal length and max aperture info). Your screen will still be off but you'll be able to rely on the blinking red AF assist lights inside the viewfinder, which is much more accurate than the screen once calibrated on the EMF chip.
