[Discussion] will a black bay pro dial and hands fit onto a 40mm explorer 2?
(magazine.chrono24.com)
More than likely BB pro hands etc., will not be compatible with a 16570 (or similar). Centre pinion will be different, torque to move the hands will be different, etc. Really not worth the effort to most likely have it not work anyway.
I'd suggest trying the BB pro on bracelet as it keeps the weight strapped down more and has a nice microadjustment to get the perfect fit.
For 15k or less you'd be in a price point to get a vintage sub with a matte dial - lot of character and would fit your criteria.
