I can't see ANY inspector accepting a GFCI trip device as a safety switch.
The general public/ any servicing tech would NEVER 'make the connection.'
If you want to use a toggle switch -- with clear ON/OFF legends....
And, it would have to be suitably labled, and in a suitable location. (proximate)

EV WHY would anyone want unswitched lights?
As for firemen responding to trouble... well, at least it's a GFCI.
Except that GFCIs fail all the time....
They fail A LOT.

You're describing a hack job that is exactly why red tags are necessary.

Which gets back to a lot of hack thinking/ engineering.
Hacks can get something to 'work' that is so screwy that failure is sure to come.
And when it does fail, first responders are expected to be miracle electricians and dope out some crazy scheme on the hurry up.
