Yes... but this process takes 10-20 minutes or more. Our backbone (which
also serves customers via redundant fiber lines) can't be down for that
long or we have VERY upset customers requesting credits, refunds, etc.

That's where peering agreements come into play.
Last case scenario you (WISP-A) just want to drop peering entirely but
WISP-B doesn't stop advertising your route, then call up whoever their
upstream is and talk to their NOC. If the /20 is your allocation from
ARIN, and you aren't peering anymore, explain the situation to the NOC
and they can stop accepting your /20 from WISP-B's advertisement.
Easy as that.

This is not correct. Let's do an example:
WISP-A is getting bandwidth from Provider A. They have a /20 network.
Provider A has to allow that /20 in their BGP filters.
WISP-B is getting bandwidth from Provider B. They have a /20 network.
Provider B has to allow that /20 in their BGP fitlers.
WISP-A and WISP-B setup a peering, but also to allow failover if
either Provider goes down. Thus Provider A and Provider B both have
to allow BOTH /20 networks in their BGP filters.
Now, for some unknown reason, WISP-B decides to start announcing
WISP-A's /20 network as local to their network. BGP will become very
confused, and thus WISP-A will essentially be down. All of this with
a single network entry by WISP-B... they just wiped out WISP-A.

They would have to have enough control to allow BGP routes from their
upstream. Technically they could misconfigure a router accidentally
and
take your entire network down. :(
That is what BGP filtering and prefixes are about. Either you peer
correctly or incorrectly and don't peer. No turning over blocks
happen.

This is great and what a reliable network is made of.
