Wife has been getting more into the idea of having large emersed plants on all tanks lately due to the success of a plant in our room on improving that fresh air feeling in the house. If an in tank planter isn't doable The smallest size budget HOB makes for a perfect diy substitute. 
All you need is some sponge, some kind of stake or trellis and Something through the sponge to make sure water has an open outflow( important to prevent the filter from clogging)
As the roots get too long you can simply pull the sponge and run them down the spillway part of the filter then reinsert the sponge
