That's what I did on my DIY skimmer. Worked well, but I found you need a larger pump as you lose a lot of flow when you do this.
A nice thing about the air driven is you can power it with a small powerhead and get a low flow protein skimmer that gets excellent contact time. The low flow you get with these skimmers is what makes them efficient.
I was quite happy with my DIY air driven skimmer, only reason I changed to a ventrui was I got tired of changing airstones every week or two.
