Did this mod while I had it all apart for the NEMA17 Stepper motor upgrade and was able to keep the leadscrew almost the height of the tower inside!
Worked out well and fit was great. Only thing to note is that the thickness of the bracket mounts the extruder a little lower to the housing, and therefore requires the knurled wheel to be moved outwards a bit to line up with the bowden tube. For this I had to also heat up the wheel a little bit to loosen up the interference fit with the shaft; in addition to loosening the set screw, and maybe moved it 1/8". All is well and printing fine!
PS - DOnt you just love the Z-banding before a NEMA17 upgrade??? LOL
