Hi Ben; welcome to the club!
The Orion electronics package only has one preamp, so no, you wouldn't be able to split the neck pickup signal from the bridge pickup signal. And even with a package that has two preamps, like the Europa, there's still just one path through the filter and the bass and treble switches. Only when you get to Signature electronics do you have separate controls for each pickup; and Anniversary is essentially the stereo version of Signature.
Of course you could probably upgrade to Anniversary electronics. An Orion with Anniversary controls would be pretty cool.
