You can mix match 11 speed mechs into your system which may not be quite what you want to do but isn't the end of the world either.
Both my bikes are running Saint shifter, Shimano 11spd rear mech and the new 4100 11-46 10 speed cassettes. I know some folk dislike the gear jumps but I find them fine and they seem to wear very well. Super reliable, cheapish and lightish drivetrain. I'll not go to 12 unless forced now.
It is a shame to loose short cage, but you do need the longer mech I think for it to work well out at 11-46.
