I can understand why you wanted to swap the teams to check for balance tests, but if the map is really balanced you really don't need to change teams.
Remove it to be in line with Valve's standards. It's one of the few things about Meridian that bothers me. That, and the final territories are too hard.
You should only team switch when absolutely necessary, like in A/D maps. You want to keep it as simple as possible.
Often times, when I'm not paying attention, I forget what team I'm on. I really should not have to struggle with this when I want to concentrate on playing the game.
This does not help by the fact that TC can already be a very confusing mode and the common HUD bug that displays the wrong colour.
No pros, only cons with frivolous team swapping.
