Actually Monfort Aquarium on Colerain was the first place I saw a planted tank with pressurized CO2. Of course this was about 10 years ago. My point is that they may be willing to do it again with some outside help. Also, Jason at Aquatics does have a planted tank with Co2 in it, he just does not always have it running. He gave me a CO2 Atomizer from Japan last week that works pretty well in my 55. I think he would be OK with some outside help in his Planted tank, but I am not sure. He also has a back room that I could ask about using if you are interested.
