Running a script inside of your snap with either /bin/sh or /bin/bash should be no problem at all. However looking at your script I see that you're making dbus calls out to the Plasma Shell, and that *will* be blocked by the strict confinement.
You will probably need to get a snapd interface created to support this dbus interface, or maybe you can use the generic 'dbus' interface and specify this service, which would have to be manuall connected. I'm hoping someone from the snapd or security teams can chime in and be more specific about what your options are here.
