Just a quick question,
If I put a noiseless GFS single coil in the middle pick-up position will work as a reverse wound pickup to cancel the hum of the neck pickup when I turn them both on?

Nope, it will still hum. The only way to rid it of hum is the add another noiseless pickup to the neck or coil split the middle pickup in that position if it's a 4-conductor pickup.
