Converting cues from Led pars to to par 64's with gel (dimmer channels)

[julian_lights]

Does anyone have any idea of a good way to
convert cues from a cue list of led RGBW
pars to work for 4 separate dimmer channels
for old skool bar of 6 pars with gels instead,
without having to re-program all the que's.
It's for a touring show that has been
programmed for Led pars thats got a gig in
an old theatre that has only Par 64's with
gel's instead of LED pars.
Any suggestions appreciated, even if its just
a good way to re-program the show so its
compatible for both sorts of par's. I'm
thinking of adding a par dimmer attribute ta
each of the colour pallette atm., but im not
sure how well this would work.
