The main issue is keeping the Z axis in line if you need to change to a tool that is not the same length and the entire Z needs to be raised or lowered.
Adjusting the Z position beyond the quill's range would require you to loosen spindle head bolts and in doing so lose Z alignment.
It is possible to modify the CNC Junior's column in order to maintain Z axis alignment, however since you have the budget a square column mill would really be a better solution.
What kind of parts will you be machining?
