What if towers on the Atlas were just boss battles ?

I'm sure we can all agree the towers on the end game map are pointless and just take up time.
I've heard suggestions of doing away with the content and instead just allowing us to put the tablets in.

I think it would be even better if towers were boss battles in one room rather than a whole map.
They can be new bosses (ideally) or a randomly selected boss from an earlier part of the game.

This will allow the towers to continue to offer gameplay and it will be more entertaining.

Thoughts ?
