I wonder if this will work as intended, with T-Mobile's International data roaming? Perhaps just turning off data roaming on the T-Mobile line should be sufficient, but I'm curious if it'll connect to IMS using the second line's data when it has a connection to its own service? Do update this thread once you've had a chance to try it out.
