Claymore, is there any chance to change the logic of pool failover?

Traditional failover (up/down) is kinda useless for ethereum pools. They usually are up, however find kadzillion excuses to reject shares.
I'm talking specifically about dwarfpool and ethermine. Time by time they catch a glitch and reject 100% of the shares.

The latest was dwarfpools "corrupt DAG". At the same time older GPUs on expanse dwarfpool with same miner (7.2) mined ok, so this was obviously issue on the pool side.
The pool is up, but 100% rejecting shares. This doesn't force the miner to switch to failover pool. As a result farm is not just generating rejected shares for half of the night, but also consumes full power for nothing.

Handling this situation miner-side is quite easy, 5 consecutive rejects = GTFO for 1 hour. I don't pretend that numbers 5 rejects and 1 hours are optimal, they are just suggestions.
