Eh. No. LOL. Trying to provide complete maps for a galactic-sized setting will just make you insane. You can't even do it if you reduce the size of the setting to a 100ly sphere, IMHO. Take a look at the Alternity Star*Drive campaign setting. It took a relatively small volume of space but was only able to detail a small number of the systems in a fairly large setting book. I say keep it big and focus on the most interesting systems, hinting at the others. Can't see how you, as a human, can do much more than that.

I personally love your map. 3D's a gimmick and nobody is presently capable of viewing and referencing a true 3D map in a useful way yet...even if you did bother to make it.
