Good theory, except....
Maestro didn't know where Rick and the rebels were.
That's the reason why they pulled Prof Hulk back in the first place, to help in the fight against the Maestro.
After Maestro found their secret hidey-place:
Prof Hulk shows up and they fight, and that exact display case is smashed:
Then they time travel back to the past, and Prof Hulk kills Maestro.
The End.
So unless Maestro suddenly, in between finding the rebels and fighting Prof, managed to Zoom around and build a brand new display case etc....
Alt theory is of course, that he and Rick both had the exact same idea of storing Mjolnir and Spidey's mask/webshooters in the exact same display case, lol.
