Uh, just flip it so the long side is hanging of the drill press platform. 
Actually it is easier this way since you get a little bit more stability.  Just
make sure you are using a board on the platform (you are doing this already,
right?) and that your depth is set so you don't inadvertently hit the platform
(oops!).

This sounds cool, but it looks one of the important features of a single
bracket--stress.  With a single bracket, there is almost no additional stress
placed on the PCB if it is attached in a stress-free manner.  2 brackets will
not support the PCB as well and slightly increace the chances of additional
stress being applied to the PCB IMO.  Perhaps negligible, but worth
considering.
