Forced re-sync

I organised a square liquidity swap, and almost as soon as I got the other 3 participants, my blockchain data got corrupted and I was forced to delete it and re-download the entire blockchain. I'm currently 14% done, but i have 7hrs left to open channels. One participant has opened a channel to another, but the remaining 3 have not because my node has been offline with this issue.

I've already offered to compensate the participant who opened a channel to the other the network fees, and offered some sats to the other participants for the time waste, as it wasn't their fault, but is there a way to salvage this swap somehow? My node is not likely to finish the sync for another 48hrs at least, possibly 72hrs.

Suggestions much appreciated.
