You might wish to delve into parameters for admission.  A Nazi Wonder Woman, as excellent an example of an "Elseworld" I've seen would likely be denied admission no?

Where would this hall of Justice be?  How do they recruit when not every world has access to the Elseworlds?

Did something like the Monitor gather them and if so... what of the Anti-Monitor?

There sorta is something like a Nazi super-woman. Two in fact. Overgirl and Brunhilde I believe of Earth 10. The Reich inspired world where Nazi Superman(Overman in this universe) whose pod landed in WW Europe and was raised by one Adolf Hitler. As far as the whole league admission thing goes, it would be more like a thing of absolutely necessity and some overlapping interests going on. What you said does raise a few good points. There would be a "prime" headquarters where the league is assembled and operates from, but I'm thinking of it being more of a space that exists beyond time and space. A purgatory like space. The Monitor could work as the force that assembles leaguers from different worlds, but I really want to go with the idea of the multiverse team being established in response to a "prime" threat.
