I don't know anything about your passive pre

but I would speculate from your description that it is not entirely passive. And, while I can't, pending more info (like, what is the output inpedance of the passive, for instance), I can't think of any reson not to hook it up as you suggest for a trial.

It may be, though, that you are simply adding a layer where you don't really need one. Perhaps different attenuators for the FP 2 might be a better approach. IIRC, the original FP 2 used 100kOhm attenuators.

But, to try it out, I would suggest turning the attenuators on the FP to their loudes position, thus removing them as much as posible from the circuit, and letting your passive do all the attenuation of the source. That is how I would start, at any rate. If you can run down more info on the passive, that would be very helpful.
