This requires simulating galaxies with distributed mass, and not a single mass at their center (as they are currently modeled). This can be done now by using a whole bunch of stars, but the simulation runs very slowly and tools to create such a simulation are lacking.

Not sure what the time table is for this feature, but it is on the list.

.... i mean like this, you know how 2 planets with rings will combine and have 1 large ring? well i mean just the 2 centers of the galaxies colliding, forming something 2 times as heavy, and random wisks of dust going around.
