Question about feature feasability

[Dboingue]

I am asking here, because perhaps, the development being fresh in your minds, you would have some sort of idea of an answer.

How much commitment or work would be required to make a symmetric UCI interface (engine both sides possible), which would display each move candidates on some graphic board display module capable of move list I/O (some hybrid of chess-ground and explorer in lichess, without the database),
and which would allow human interaction at each move, either choosing a move line candidate of another move that the human wish to explore?

Any existing software elements that could be part of this? sorry if this is not appropriate, I thought it would.

Or any suggestion as to where I would get some answers, or how to formulation that question better (i have a similar question on chess stack exchange, this one is more general, but could also be improved).
