I used to play at a server that had this and it worked out pretty well. People who died were able to kill some time while socializing with the opposing team during their deaths and you can get some pretty good laughs when you kill someone and give them shit for it over the mic lol. 

Plus, it makes it easier to pass votebans for mic spammers because then both sides can hear the mic spammer making the voteban more likely to pass.

Just some food for thought.
