Update: After a lot of good advice I'm thinking the old design was not very practical, so I've redesigned it as an 20" F3 and the secondary 8" f2.75. I've done full sized ray tracing and its shown to drop the overall length by 1.3 meters. I know the f3 will be a challenge but its nothing a bit of patience wont fix.
