I would. Then load on a large homemade toroid on the top to get
your frequency back down.

Compressed air.

Heavens no it is not scrap. If you play things right when cutting
the coil down you can get a pair of matched frequency secondaries
with a pretty decent Q factor. These open up lots of doors into
areas such as large 1/2 wave systems, wireless power transmission
experiments, etc..

As long as you are not seeing bounced messages then either
address is fine.
