You could but it would eat up batteries pretty fast. Here the spring keeps the door lock, and when it gets power it charges the electromagnet that pulls back the pin to unlock. If you invert it you would have to flip that some how where the power is always on pushing the pen to keep it locked. What i would do is have a way to supply backup power to the unit. For example i have a electronic lock that i use on a door in the house. The batteries are kept inside the locked area, so if the power goes out there isnt a way to access it from the outside. So what the company did was put a connector hidden on the outside, so if the power went out i just had to connect a battery to the front to power it long enough to open the door.
If its a simple electronic one that just needs a current of some kind to open then it should work fine.
