I'm not totally sure if I understand you however, you CAN use the middle part(atleast a portion of it) to add live rock to add more beneficial space for bacteria to adhere to! I would have to stress that you don't use sand in it as the flow, IMO would only get caught in the return pump!
Amiracle Pro-line Wet / Dry Filters With Protein Skimmer, Amiracle Pro-line 1000 Wet / Dry Filter W Pump ( 10-75 Gal Tank )
Is this close to what you have?
IMO, venturi skimmers suck as they get junked up easily(air diffusor/stone) and their performance diminishes once this happens, so if you plan on using this type of skimmer, you will have to replace the airstone continuously!!
A skimmer is a wonderful and important addition to a tank so I guess my point is to try out the venturi skimmer and see how efficiently it works!
You may want to place a piece of foam to help trap large matter from getting lodged into your pump if you do in fact intend to use live rock instead of the bioballs!
I personally would use live rock at the expense of the bio-balls as I set up my sister's boyfriend up with the same transformation!
Hope this helps!
