Personally, I would not recommend doing this...
If at some time, you decide to play your 10-bit encodes using a hardware media player (ie: STB, Blu-ray player, Smart TV, etc) - they wont work.
EDIT: Any software media player which offers GPU decoding, won't decode 10-bit encodes using the GPU. They will decode using the CPU.
