AR question

I have a couple AR 15's in 556, nothing fancy, just PSA's, and a really nice Mega monolithic rail in 6.5 CM. I love the Mega, it is deadly accurate. I've been thinking about different calibers so the question is, what calibers can I switch to on each rifle. Second question, how will the lowers mate with non matching uppers, like an LMT or LaRue on the PSA, or anything desirable on the Mega? Mostly looking at the 556 as they are a bit more affordable to shoot. Pro's and Con's of various calibers? Thanks
