I think that if you Capsize the Academy, then even your version wouldn't fix anything, because infinite mana can still be generated. Am I right?
This should probably be what Tolarian Academy is:
Tolarian Academy v. 2.0
Legendary Land
Tap, Remove Tolarian Academy from the game: Add U to your mana pool for each artifact you control. At the end of the turn, put Tolarian Academy into play under its owner's control.
Also, here's another thing:
High Market v. 2.0
Land
Tap: Add one colorless mana to your mana pool.
Tap, Remove a creature you control from the game: Gain 1 life.
This prevents you from sacking a Rector to it and getting Bargain. In fact, High Market was the culprit for W/B Bargain's brokenness.
P.S.: If fixing broken cards was truly R&D's job, this discussion wouldn't be happening right now because none of these cards would have been printed.
