Home Game Tourney of Champions... Good or Bad idea?

[PShabi]

I host a weekly home SNG. $20 buy-in. 2nd place gets entry back, winner takes rest.

We've got a core of 5 player and usually 1 or 2 others guys to round out a field of 6 or 7.

If you played at the game, what would you think of this idea.

Take $10 out of the pot every week, and put it to the side. In December, anyone who has won this SNG throughout the year would be eligible to participate in a freeroll for the money that was pulled out of the weekly pot.

If you did it all year long you'd have a nice $500 freeroll at the end of the year.

If you played at a similar game would you like this idea? Why or why not? Just something I'm tossing around to give some added flair to the whole thing.
