Yes, I already love the current vortexes that appear in the game, but I believe we're missing a few vortexes, and it would be cool to have some more detail to some vortexes (could be enabled in mod settings)

 1st, 2nd and 3rd doctor's vortexes can be diamond or currently hexagonal, but mirrored. I figure this would be easy to implement because of lesser detail needed.

3rd and 7th doctor's other vortexes can be spiraled.

11th doctor's vortex will be difficult to make because of the clouds.

12th doctor's vortex is not needed, but clocks would look cool. Would be too hard though to make, I suppose. And too laggy on the servers.

Just something I'd like to recommend. Have a nice day, whoever's reading this.
