You can't.
That said, don't be afraid. There's no reason to assume the profiler does a blackout on stage.
If your tube amp died you couldn't play on without a short break either.
Damn... I hoped it would work somehow 
It's not the Profiler I'm worried about... you can always have blackouts on stage due to shitty wiring or something else that blows a fuse.
i do want to eventually look into this, but won't have time for a while. but I remember this coming up and that the profile that loads is the default.kipr file that you can find in a backup. thus I'm curious if that file doesn't contain complete rig information (ie, it does not have stack or effects data). i know someone tried to edit it to include delay/reverb, but that didn't work. but I'm wondering if you could copy/paste the profile data from the desired rig into the default.kipr file, overwriting the default profiler data...
