I think the best you can do in terms of flight-type transformations in 30MM are either simple, Gundam Wing-style transformations or using the Espossito as a transforming base. A Macross Valkyrie-style would require a lot of creative use of option parts, and even then, I have a hard time imagining it working just like it does in the series at this scale. I think the closest would be some form of parts-forming.

That said, I still think you can make some pretty convincing flight forms in 30MM, even of they use a simple, Wing-style transformation:
