I'm working on a dual nozzle set up at the moment, but my system utilises a secondary lifting nozzle. I'm hoping the standby temperature feature of Duet will be enough to stop oozing.
You may want to consider a detector built in to see if the new tool has been picked up. There is always a chance for a magnet to detach, and a small microswitch will stop any print failures. The software just needs to know when to expect it to be detached.

As far as I'm aware, you'll need to make a script that asks if the endstop is currently triggered or not. This script would then end when a tool change procedure is initiated, and would restart once it has ended. If the endstop is not triggered on normal print procedure (not tool change) then printing will pause and wait for assistance, or alternatively it will retry docking / undocking x number of times.
I don't know anything about scripts for Gcode, but there is a page on S3D that explains some nice tool change scripts using IF commands. https://forum.simplify3d.com/viewtopic.php?f=8&t=1959
I'm going to start looking into more scripting like this I think, it adds a lot of functionality outside of standard slicing.
