Are black holes all thought to be homogeneous internally, or is it possible for a large enough collection of massive objects in a small enough space sufficient to create an event horizon?

I have a layman's understanding of physics and astronomical phenomena, so please forgive me if this question is absurd.

However, it occurred to me that it might be possible for enough material- such as suns and so forth- to be in such close proximity that their collective gravitation creates a black hole to outside observers, even though it isn't really a single blob of matter- but for all intents and purposes it would still appear that way to outside observers.

I guess my question is- is this possible, or is it something that would be rendered impossible by the requirements for how dense a mass must be to create an even horizon?

Thanks!

Eclectic mixtures of matter inside the Schwartzchild radius will form a black hole.

They won't stay eclectic mixtures of stuff, however. 

An outside observer will only be able to tell their total mass, total charge and total angular momentum. Nothing else.
