As far as the clogging of the filter. Just drill a second return at the max level you want to allow in the filter and run it to the tank. So if it clogs it's will just overflow back into the tank.

well the filter being above the tank and gravity fed would run dry if there was no water being pumped to the top of the filter. i still think its my best option. its going to be a stingray tank so filtering from the bottom will help. plus ill being doing a drip system too so that will skim the surface. I think it will be a very clean tank
I have DIY overhead (or "dump" filters) on all of my large tanks.
Just support a clear rubbermaid container over the tank. Drill several holes in the bottom of the rubbermaid (to allow water to return to the tank via gravity)....and run a pump (from the tank) to it. I plumb mine with PVC.
Fill the rubbermaid with (from bottom to top): a couple of grates of eggcrate (to prevent blocking the return holes), the bio media of your choice (bio balls, scrubbies, lava rock...whatever), something to distribute the water (I use Poret filter), a bin with a bunch of holes in it...filled with the mechanical media of your choice.)
Done...

I just spent like an half hour on the drawings and it didn't save so ill just explain it and as long as everyone else thinks its a good idea, ill draw it all out again.
It seems to me like it would work, but I'm no expert.
tank plans: 96"x48"36" with a 90"x30" viewing window
My tank will be built into a wall in a small, heat/humid controlled room. since above the tank will be behind the wall, I figured an overhead filter that drains into the tank would be easiest. Starting with a large Rubber trash can (32 gallon) positioned with the bottom of the trash can slightly above water height in tank. 2" drain from bottom of the tank to 4000-8000 GPH inline pump/pumps depending on size of tank. Water pumped up to top of trash can. 2" bulkhead into the side of the trash can into a removable multiple 1" bar sprinkler system. 6-8" down will be a perforated tray with a few inches of sponge filter on top. 4" below that tray will be another perforated tray with bags of chemical filtration on top. Under that tray will be a couple feet of bioballs and scrubbies held up by another perforated tray about 4" from the bottom of the can. under that tray will be a bulkhead with a 2.5" return drain to display tank. I will probably have a bulkhead through the back of the tank for the return from the filter to make it easier to cover the tank.
Any problems?
It says here u would drain from the tank too inline pumps. The tank would not drain if the power went out because the plumbing up to the filter from the pump would be a higher point anyways. Pumps shouldn't run dry unless the tank runs dry... and run a safety overflow back into the tank at where ever u want the max point of the filter to be if clogged. Done deal.

Sorry, I wasnt paying attention. you are right the pump wouldnt go dry, I was thinking of the filter running dry. anyway, I'm looking at another design now. still using a trash can but having the water pumped to a 10-12" tube down the center of the trash can with mechanical and chemical filtration in the tube then fill the trash can as a fluidized bed filter with air pump "moving bed" up to a drain about 3/4 of the way up the trash can. think the head pressure in the 10-12" tube would be able to force the water through the rest of the filter to the return drain?
this is making my head hurt

Either would work. But a fluidized bed filter will require more of the can to be filled at all times so you have the weight to factor in again. But other then that it's the same concept.
