Actually the standard Bachmann G-scale track IS interchangeable with Aristo or LGB with the slip-on type connectors.
Carefully twist and remove the black metal tongue that is on the ends of the Bachmann track. Be careful to not twist too much lest the track become bent. Then it is a simple matter to gentle pich the Bachmann track and slip it into the Aristo or LGB slip-on connector.
I have mixed Bachmann and LGB track for indoor Christmas layouts with no problems of electrical continuity. I don't know if this will work outside but since even a light dew will cause Bachmann track to rust-over I doubt this is a technique with much value outside.
If you want to restore the Bachmann track to its original condition simply save the black metal tongue and carefully re-install it.
