Yes, this should work fine.

Regarding domains with different RPs and synchronizing state. I think it
is generally a bad idea to have multicast source activity in one domain
pushed out to every other domain, even if they are not interested. There
are generally operational issues with MSDP and I don't think another way
of doing it would be better. I'm hoping SSM will be the way to go for
interdomain in general. Embedded-RP is a pretty good solution though.
