intake and outtake for a sump

I would worry about one of them dying, or getting clogged, and then you end up in a situation of either the tank or the sump overflowing. Not a wretched idea, but I could see problems with it.
If you have two canisters, why not just hook them up to the tank instead of trying to rig up a sump?

I already have an FX5 hooked up to the tank and was thinking of just hooking up the others also when I came up with this idea.
I was think if I had the intake close to the water line if one canister went down the other would not have much water befor it went dry, maybe crazy
won't work
this is becuase one of your canister filters will have to deal with head restriction (gravity is working against it and so will flow slower) the other will be pumping with gravity and so will pump faster eventualy overflowing your sump or the canister will end up running dry.
not to mention canister filter pumps arn't designed to deal with any ( or they can only deal with very little) a canister filter works by forming a siphon in the canister and tubes when not running the water line inside the tubes will be where the water level in the tank is the pump merely pushes it the other 2-3 inches over the lip of the tank.
you need an overflow (whether DIY or store bought though DIY is cheaper) and a proper submersible (or inline if you want to drill holes in your sump) pump

Yeah, the sump will overflow in less than 10 minutes, guaranteed.
If you have a canister on a tank now, take the outlet and lift it 3-4 feet above the water's surface. Note how much it flows. If it will even pump at that height, it'll probably be about 50gph.
Now, take the same outlet and lower it 3-4 feet below the waterline. Note that it's flowing about 1000gph.
