Yes, that would be easy . . . except . . . you can only override one pressure switch at a time or overload the system.
You need one switch each for the up and down. In the event of a problem you have to make sure you push the right switch.
If you come up with some more complicated wiring, you could make it work with only one switch for both up and down but you still have to push the button if something isn't working as required.
. . . or . . . you could put in a completely automatic system . . .

Seems to me the simplest and least expensive option would be to install a momentary on switch in the cockpit to override and close the open pressure switches.

Just my 2 cents.
