Adding longer hoses to a small pump may not work very well. I know they work from the siphon effect of water falling from the tank, through the inlet hose to provide some of the power to push the water back up hill, but I still would not add more tubing with the goal of putting the little canister farther below the tank than the manufacturer suggests.
If the tubing is long enough already, go for it.
The smaller Eheims would be a good choice, too. I would look at the gallons (or liters) per hour, though, not look at what size tank the filter is rated for.
