The Choice, with positive marketing

This is my first FanPost, so if I do something wrong, I apologize. Also, the title "The Choice" was unfortunately taken.

Here is my idea:

Is there anything stopping a superstar (and of course Melo is the one that can go into free agency first, so I'll use him as the example) from doing the following? Melo could do his "decision" on tv, much like LeBron, except instead of him announcing where he was going, Melo would turn it into a fundraiser for his preferred charity. Melo would have his list of teams that he is interested in going to (with contracts already in hand, waiting to be signed), and people would call in to donate money to the charity. The donor would get to pick a team for this money to "count" towards, so that the team that had the most money donated in its name would be the winner -- and get Melo to sign with them.

For instance, if OurDay called in and donated $20 to the charity and picked Charlotte, then that would count towards Charlotte's running amount.

It seems like a good way to raise money for a charity and allow a superstar to get out of their current city with less fuss. Obviously, Melo would not have to pick Denver as one of the teams.

I realize that there are some problems with it (for instance, MJ donating for him to come to Charlotte) that would have to be resolved. However, this would put a positive spin on Melo leaving and raise a lot of money for a good cause. What do you guys think about this proposal?
