From what I've seen Fencer has no intention of creating a board for Fisher chess. It's more likely that (from what I saw on BK board) he is going to shrink the smaller boards due to the low usage of them. If people want a Fisher Chess board that badly then it can be asked for either on the BK board or on Feature requests.
