Is there a reason *why* you don't want to switch it the
same (original?) way?
The Altair MITS 8800 also has an AC switch set up this way, which made for
"interesting" times when probing. A compromise might be just to cover the
traces with something that will avoid any bare conductors "zinging" you,
such as PCB resist. Althernatively, one could simply bypass the switch on
the front panel and switch the mains power externally--that's a change that
can be easily reversed.
Just some food for thought.
