Interesting.
They would certainly have to be a lot smaller than what we currently assume we are observing. That's a lot of mass that would be relatively close together.

Well, the mass contained in the Milky Way -- the visible disk -- is 2x1011 M(Sun), the mass contained in the Milky Way galaxy -- out to as far as we can see HI gas -- is 6x1011 M(Sun). Our galaxy alone expands to over 100,000 light years in diameter, so we're doing a lot of compression since we can see much further than that and you'd have to take into account all the other distant galaxies.
If we assume (as a lot of people do) that 90% of the universe consists of dark matter with gravitational affects, in a 6000 light year universe, we would most likely be facing implosion already.
fixed typo
