dia=90mm fl=910mm
however I am willing to go for a shorter fl if i can get one, just means a slight tube mod.

Could be smaller than you weant, but there is a Williams Optics upgrade that sells just the lens, 80mm.

How about a 90mm f/7 (a bit shorter ;) ) but US$520? Back when Ambermile was considering making scopes, this was on offer. They are in Hong Kong, lens is 90mm F/7 doublet FPL-53 APO w/cell.

If you're interested you can email Michael at great-eye@mail.com
