Need feedback on my custom motor housing design(reddit.com)

I recently came across a very affordable 8115 45kv (0.3ohms phase R) motor kit which includes a wound stator and a steel magnet ring . Quickly modeled a mockup in Fusion : https://preview.redd.it/ckbo2a7d5h7h1.jpg?width=1043&format=pjpg&auto=webp&s=40716922ce7ca2358503ede09badaa0f0de7417c https://preview.redd.it/rrtz8qvd5h7h1.jpg?width=1280&format=pjpg&auto=webp&s=9b356dfab5d5953781b3e0b4d9fcb25fb3f2a37c Instead of using a pressfitted central shaft like most bldc do , i opted for a pilot diameter directly on the rotor to locate it on the 52x40x7 bearing (possible stiffnest improvement ?) then use 2 bolts ,circular nuts, a plate to preload and lock the bearings and rotor to the stator. I'm also using a very shallow bearing seats with both 7mm thick bearings lightly-pressfitted in to shallow 3mm seats. Would this work or this housing design need to be scrapped immediately ?
