You can obtain the destination set IP from $dd, or $(du{uri.host}). However,
you can't just modify the To URI like that.
You will need to do it in a way that doesn't break standards-based
proscriptions about what a proxy can do, otherwise endpoint A can look at the
modified header received in responses from endpoint B and say, "I didn't send
that!"
Kamailio provides such a mechanism. In brief, it conceals the in-flight
alterations to the To URI from endpoint A:
