And again the same answer: Very doubtful. The developers already decided to abandon this part of x265, because of reasons:
- twice the efforts to make assembly routines with fewer and smaller CPU registers in 32 bit CPU mode
- half the available RAM because 10 bit precision per color channel need 16 bit RAM instead of 8 bit for storage, and the limitation to 2 GB (or 4 GB for LAA processes) does not even allow encoding of FullHD (not to mention UHD)

Damn, something delayed my reply remarkably. I thought I posted it right after the question...
