I concluded my research on this topic... sadly, it can't be done.
TL;DR for the curious, don't make maps bigger than 8192 px, a 100x100x81 setup is the biggest I could manage to do.
Point by point.
The biggest of the issues is that the client can't handle an image bigger than 8192px. Because of that, the biggest worldmap I managed to make was 8100x8100, thats 100x100x81.
The second problem, as I already said, is that even if the server could handle a 100x100x500 setup, I have no way to test it because I can't compile a 50000x50000 png image (not even a white flat one), because of that, the biggest map I could manage to make the server load was 10000x10000, but the client would CTD trying to load it. Unless you are ok with a black map on the client side, I wouldn't recommend this.
As a final note, I wasn't able to make the server load this grid worldmap image idea I was talking about, this is what I tried so far (ugly coding):

The result was the server loading only the first image, so the player only was able to move inside a 10000x10000 worldmap (black clientside of course).
I'm dropping any further effort on this, since the client can't handle large image setups (not even sliced little images), I don't think it's worth the trouble.
