Yes, that would work.
I'd say that for such an opening fight the Wrecking Crew would also work... so at the at start of the film, we see Thor on Midgard fighting four super-powered criminals who had found an Asgardian artifact that accidently looks similar to an earthly crowbar and that also accidently dropped through a wormhole during the event of the previous film (= the source of their superpowers). At the beginning of Thor 3, it is Thor's duty to find and regain such lost artifacts. So that could be the MCU's version of the Wrecking Crew (which, of course, Thor would defeat with ease).
Or if the film's script would be in need of a secondary "big beast" apart from Surtur, Fafnir would be nice. The Midgard Serpent, however, would deserve to be the centre of its own movie.
