Will my 650nm design work?

Hello
I dont know alot about pbs cubes so I was wondering if this design would work. Im trying to make my quad block work, I dont want to buy new holders. So will the red beams combine like this?

thanks

the polarization of the diode going straight thorugh the cube should be different to the ones coming in from the knife edge setup.
you need to rotate each diode until you get maximum output from each one.
