OK, I see 36" is a common size among many speaker stands on Amazon. That may be the best you can do without extensive searching. I may actually have 36" stands, I completely forget now.
Do you think 36" could work for you? I don't know if you know this but you want the tweeters ear level, not above. I realize everyone has varying preferences, but 36" + ~12" should give you more height than you need. I currently have my speakers, the Energy CB-10, arranged exactly as you described. So, the Sanus brand is affordable and I would definitely recommend.
