Thanks glye
I have to consider only what I have available here in Turkey. Due to latest customs regulations only packages below EUR 150 in value can be imported as personal items (you still pay taxes) anything above it requires full customs clearance procedure. So I can’t even order XDR hub from Germany which Jipe referred to, even if I wanted to.

Also these are expensive toys and I need warranty coverage, not really possible when ordered from abroad.

Regarding brakes, did you consider upgrading to Deore XT? Regarding front rotor, do you think using RT86 with opposite rotation (front) be an issue?
