Need help saving my temple

So I made the mistake of closing the loop on my snake. I know my only hope is to get a sacrifice chamber medallion to remove that loop and keep my snake alive. Are there any other strategies that can help mitigate the destabilization of rooms other than locking the end and hoping the middle of my snake doesn't get destabilized? Here is a link to a temple planner of what my temple looks like minus the random rooms that aren't important. The generator is the mistake.
