In general, you can't do anything with world gates or dimensional manipulation with handwavium. You can't even use "hammerspace" and create dimensional pockets, or do much with sub/hyper/para-space, apart from the standard FTL communicators and the standard FTL drive.

The wiki makes it quite clear than no one knows how to get consistent dimensional manipulation with handwavium.
However, Legend of Galactic Girls has visitors from out-world (travelling using magic - magic isn't obviously available in Fenspace) and one of them used a dimensional pocket. The Professor (only slightly Mad (I'm lying
) implied that he'd previously met other examples of dimensional pockets in Fenspace (presumably made using handwavium), and the implication was that those had the same signature as a world gate.
Now, you might say the Professor is delusional, but if so, his delusion told him the Girls had arrived, and, later, matched this up with use of a dimensional pocket. But, the Professor seems to be at the outer limits for those who use handwavium.
