Is it OK to place two litters of 6 week old kits together?

[clalso]

I'm considering placing two litters of 6 week old kits together in order for the mothers not to have to nurse too long. I do not have another hutch to move one of the does to her own cage. Can I put two litters of 6 week old kits together without concerns of them harming each other? I figure I just need to be sure I don't want to wait too long to find the kits new homes in order to avoid breeding, but I'd do that anyway if I was not mixing litters of kits.

Yeah, people mix litters of kits all the time, they should be fine until they reach puberty
