I thought about the rules and am concerned about a few things that might be related.
First, it seems like there’s a danger of accidentally ending up in scoring, for example if everyone suicides, which doesn’t seem very Go-like.
Second, there’s nothing much like a normal ko feature, blocking someone from immediately recapturing a single stone, as long as it’s recaptured with new colors or there’s action elsewhere on the board.
Third, presenting the board diagrams seems difficult when there is a potential for complicated interactions between stones that then get removed. You might find yourself having to post two board images per move, to show what happened.
If captured or at least the suicided stones could somehow stay on the board until the next round, maybe that could address these issues? (I recently proposed something like this as a delayed capture rule for normal go.)
