Multi-algo should be on the table.
Such a fork doesn't touch upon fundamentals, just improves security protocols.  There is a test net.  Plenty of time to play.

I think it is a matter of copy and paste too, digi, digital have MM multi, the best option might be adding the XMY-groestl flavoring no?

Another thing is I was wondering if any of the POW have a 'unfreeze' mode, or simple timer, that recalculates the DIFF if the chain gets stuck for N-seconds.

Last but perhaps more debate-able.  master nodes.  this seems to be a proven method to pay the node keepers.

The toll/tax could be just rewarding 1 out over every 300 blocks to the longest uptime servers.  That's just 0.333% of the rewards.
