Stars VIP for SNG player

[jmillerdls]

I have yet to do much of the math to figure out how good this turns out to be, but I have a question.

At Stars, can you use T$ for SNGs? If so, is it not conceivable that you could use your FPP's for entry into the Sunday tournament, then unregister for the T$, then use that T$ for SNG's, thereby increasing your SNG bankroll?
If this is the case, then SNG players can get cash back for the FPP's essentially..right?

Someone fill me in on why this won't work.
Oh, and if someone has worked out the amount of tournies you would need at different levels of SNGs at Stars, I'd love to see that info. Thanks.
