Realistically I can't promise that. But I think with very small patches this board can work (it already does, minus the ethernet and armbian-install).
I will try to solve the problems in this board and then post my solution here (as a single post, not as a series of posts). I don't think it needs to be added to the list of supported boards as long as this thread is indexed by search engines and someone else with the same board can use these forums to successfully install armbian on orangepi cm5.
