I really can't offer much but if I had to work something out knowing as little as one could about this I would start by simply having the person attempt to address a print on you unmodified press . From there you should see interface point that need attention, example height, reach etc.
You might also think about a different squeegee configuration; attached is an idea that might help. Basically a squeegee on a "reach handle" that allows the squeegee to pivot say 20 to 30 degrees to aid the reach / flexibility in the flood / print stroke.
the attached are pretty crude but you should get the general idea.
best of luck, where there is determination and drive there is success.
