hello Ric
1)ok fair enough sounds like a preference thing
the diagram above should help with that
2)pots all audio? cool
only caveat would be that the CTS come with a slightly larger diameter threaded shaft
and you may need to open the holes a bit to 3/8 inch
not hard just be prepared
also when putting capacitors on
be careful that the legs don't short to ground before the capacitor
3) your pickup selector switch
its the Toggle style right?
like this

and you want to swap that with a 5 way blade?
I am not familiar with a 5 way switch that would drop in with out some body modifications
4)I put the Seymour Duncan Hot rodded set in my RG2
these cover the classic 70's rock well
and with the right pedals do the 80's hair band too
and I put the Carvin S22 covered pickups in my RG4
heck I just loved the look of the no holes chrome covered pickups
the 11 poles per coil eliminated the F-spaced vs traditional spaced debate
they are warmer and sound decent split
but not single coil at all like the SD pickups do
the style of music you play will play a much bigger part in which pickups you exchange them with
if at all
( those Duncans should be replicas of something in the standard Duncan line )
if you could post the resistance reading it may shed light on which ones
to take a resistance reading
with an multimeter set to ohms
plug the guitar cable in to the jack
select the neck pickup with the selector switch
turn volume all the way up
on the other end of the guitar cable
one lead to the tip
one lead to the sleeve or part just below the black ring of the jack
should read something like 7.5K or 8.5K ohms
repeat for the bridge and and post results
or just got to the SD site and compare the resistance with their standard line
that should narrow it down a bit
