I can't really see a good fight between Brandish and Dimaria.

Either Brandish is completely helpless bar interference from Ultear, or if Brandish can shrink someone's ability to use magic, then Dimaria is completely helpless. Unless of course Dimaria somehow lost that ability or doesn't want to use it, which would both be stupid.

I think this is going to be more of an emotional confrontation and psychological matter rather than the two duking it out.

Actually the only person who might have a chance to not be affected by Dimaria's timestop that I can think of (other than Ultear obviously) would be Lucy, but only if she's already in a Star Dress at the moment when Dimaria stops time. The somewhat stretched (but still well within Fairy Tail "logic") explanation would be that the connection to the Celestial Spirit World, where time flows differently insulates Lucy from the timestop.

After all Celestial Spirit Magic is the key component for the time-travelling of the Eclipse Gate, so if anything can throw a wrench in time magic it'd be CSM.
