I'm wondering if I can repurpose the hinges that I have already.
do you have the swing door hinges or just normal hinge -hinges?
Re building an aluminium door frame to be smaller is possible - I've done it on a sliding door. It helps to have a chop saw to keep the cuts square.
The arc/swing of a .75 m door in a 1m shower tray should leave enough room for you to open the door and get past, and a frame-less door in 10mm glass looks much nicer.
