With a lot of time and energy, yes. (Or at least DX12 can be – I don't plan on ever supporting the legacy APIs). However, I don't intend to support them in the near or medium term; the Vulkan implementation still needs a lot of work, and even that I only work on occasionally in my spare time.
Of course, if someone else wanted to work on adding DX12 support I'd be more than happy to help with that.
