Experience with having CTY integrated as the gifted "pull-out" school wide?

In case we don't get lucky in the lottery (I am waiting for a citywide gifted school -- the accelerted program) (all 99th percentiles go into a lottery for the available spots).

I am looking at using CTY as a pull out in our zoned school, which is really good with a chess program etc. The PTA is super strong and influential and I am rounding up support. And the NYC DOE dept for G&T is supporting me. I need to present to the principal. I do not know how easy it is or how much CTY will help. I am in contact with them, but just preliminary stages right now.
