I see FFMPEG supports capture over BMD Decklink:

Maybe worth looking into as an alternative if you are familiar with FFMPEG. I don't know how feasible it would be to capture and encode to x265, tone mapping included, as a single command operation. You'd have to research the subject and test.
You could certainly do it with FFMPEG as a two stage process - capturing first to a 10-bit YUV422 'near lossless' intermediate, like DNxHR HQX. But I can't see that would offer any particular advantage over your existing two step process - I'd stick with VDub2 capture to Cineform (Filmscan 2) if that works for you. Just bear in mind that the resulting bitrates (and so file sizes) of your Cineform captures will be somewhat dependent on the complexity of the video content. But the same applies to lossless formats, like MagicYUV, also.
