As Henrik said it sound like you are on the right track However I would
make two suggestions.
It's slightly too late for 3.0, take a look at the 3.1 code instead.

In order to make Squid select some SCTP and some TCP you may also need
to look into an ACL control for people to setup their own decision
logics of when to try each. With a failover, as a first guestimate I'd
think SCTP when asked, with old TCP as a backup if it fails.
