Your 2nd design is much better. You can do it with one pump and tee off to fill the fuge. Might keep some heat and or noise down from the system.

Thats actually what I was going to suggest Im picturing a 6 wide x 6 deep well the length of the tank built into the canopy water pumped in on one end and overflow leading down to the tank on the other end. It would be low volume enough so the weight of the water wouldnt demand that much structural support
 
That is not to criticize your main idea. My only complaint is it takes up additional space or adds another tank to the room. I like the idea of combining/condensing. Im in the midst of building a lizard cage that will double as a stand for a 125/180 gal tank with two snake cages built into the canopy(of course I'll post pics if/when it comes togehter).

If you went with the above tank refuge in canopy I would use moss as it's low light and is documented to be a decent nitrate eater. Then I would put lilies or lotus flowers in that would stand up above the water line being decorative and visible to the room. It's also going to be easier to pull it off with your girl's blessings if you pick pretty flowers...
The side tank would be more traditional as far as th eplumbing/design goes. I'm not very well versed in high end planted tanks. I know a lot can be done but I wouldn't even know where to start. I'm sure if you put the reading/planning in you could go as elaborate and decorative as you want.
Dane, if you put the refuge at the same level as the main tank the water levels will have to be equal. It could work, although all of the overflows would have to be perfectly level and the sump below would have to be able to hold a lot of extra water when the pump is turned off...
You've got a lot of options to do what you're thinking... you might want to take your girl out to dinner and buy her a new skirt or something before bringing it up ;-)
