One reason this idea wouldn't work is because if someone found a way to abuse something as a trial to get lots of free money, they could do so and if they get caught, big deal it was a trial account... but if they don't get caught, they could upgrade and have tons of $$$. But if they weren't trial to begin with, not only would they be less inclined to try to abuse a bug or hack, but it would be a lot easier to trace them.

It's a nice idea in theory... but I doubt it would get people to upgrade. Trial is just what it means... a trial. Not "well there's the exception that you can save all your monies in a bank". Trial accounts are only supposed to allow a person to test out the game and some servers... not play on it for months without paying while still earning money like everyone else.
