No, we don't support views yet.

You'd also need a custom sssd.conf as well.

We support this kind of configuration in 3.x. Using multiple --server 
and --fixed-primary options of ipa-client-install you can add multiple, 
hardcoded servers and still have failover. Basically you configure 
things to ignore the SRV records, so you shouldn't have to mess with the 
resolver at all.
