Yeah, I agree that separating them isn't all that difficult, but once you do that you'll have a 90 or worse an s bend in the conduit - if and when you replace something you have to pull the cable thru that, which while doable isn't fun or optimal. A pic would help, but I'm envisioning that you have a large 120v box with 3 120v light cables tied to one 120v switch source for the lighting, and a separate 120v switched feed tied to the cable running to your power cover. So 5 or 6 conduits - one or two for the 120v in 4 for the 120v out to lights and motor?
As above, the bond is important and different, don't disturb it when you working in the light niches. It should be number 8 copper tied to anything metal in or around the pool-its to ground out stray current that can exist independent of the pool circuitry .
