No sure about support profile since I don't use it.
What you can do to stop iMessage going to the iPhone is
go to Settings > Messages > switch iMessage OFF and in Recieve At delete your Apple ID and Caller ID.
Also in Settings > General > Reset > Reset All Settings.

I have read that it is registered using my Telefonica number and furthermore the Device ID, which is unique. Your work around will prevent the delivery of any further iMessage to the phone? Great! I will test it.
