You could go with a base from LLL reptile and modify it by drilling a hole and pitting a bulhead and some tubing so you can drain the water that collects. Or sell the reptibreeze and get a dragonstrand cage with drain pan.
You do not need the full spectrum light and it looks pretty bright. It may be the reason the chams eyes are closed. Only need UVB and basking. I would recommend switching from a UVB bulb to a tube, and t5 is better than t8.
Yes, I have experienced this several times with female panthers. Not to overly alarm you but the sooner the better with the treatment. I waited several days with one female and she did lay and live a long life but never was 100% again. She was always much more sluggish.

First problem I can see is you need a new cage to separate the females. They may look ok but they are causing un-needed stress. That may be one of the reasons why they are not eating.
IMO, I suggest also getting rid of the silk plant. You say you watch him closely, but if you come in and the plant has a big bite out of it, what now? lol I bring this up again because I have had a veiled that ate some of the fake plants and had to go to the vet. I always errored on the side of...
I have owned both the mistking and AquaZamp. In terms of quality of components, the AquaZamp is better. Remember, a misting system is not a super complicated system, not many components, and they are pretty similar. I love the aquaZamp but I have heard complaints over the last several months...
