Randell,
I'm not sure I would think about your proposal as a series 3. The term series really refers to the style of pickup (single coil) and the supporting electronics, while the filters are a separate matter - the (two) filters you get on a Series 1 are identical to the one or two you get on many of the non-Series instruments.
The only special case here is that with a Series II, you get CVQ (continuously variable Q) knobs instead of multi-position switches, and Mica has stated several times that you can't have those on anything other than a Series II, because it is difficult, time-consuming, and therefore very expensive.
As you probably know, Series electronics usually require two control cavities, and on a smaller bodied instrument such as the Rogue, the body also has to be enlarged to make the standard cavity bigger. So my guess is that squeezing in the extra stuff to convert two standard filters to two full channels of an SF-2 would be pretty much out of the question.
On the other hand... now that Paul TBO has let the cat out of the bag, I happen to have a Rogue (with non-Series pickups) in which the (single) filter is identical to one channel of an SF-2, and it somehow got squeezed into a single cavity in a standard Rogue shape.
The filter can be assigned to either, or both, pickups; has the full frequency range of 45Hz-6kHz; CVQ, low/band/high pass modes; and has two knobs for mixing the direct and filter gain for whatever pickups are assigned. In addition to that, there are master volume, pan, and bass and treble pots.
Ignore the control layouts in the FTC thread referenced above, those were thrown out a very long time ago. But Dave - now you should understand what the 'filter mode' switch does :-)
To me, this is a wonderfully flexible circuit - I can mix in some highs from the neck pickup, or deep lows from the bridge, as a couple of examples - and I wouldn't change a thing about it. Ron did an amazing job, even more than I asked for, but it turned out to be much more difficult than any of us imagined. There are several custom circuit boards, I think all of the pots were hand made, and you wouldn't believe how crammed the control cavity is - for a single filter, and without the Series stuff.
I'm not sure how much more I should say about it at this point, I've been waiting for some guidance from Mica or Susan on that. I gave them a check for more than twice what they asked for the electronics upgrade, and they still lost way more than that, but now that the design has been worked out, they may be able to offer it at a reasonable cost... or it could be that Ron just doesn't have the time to fit these in with all his other projects.
In any case, I suppose we'll have to get some pictures up one of these days.
