Might be worth your time to watch craigslist for a cheap top that includes the frame, especially if their fabric is messed up. I really doubt you could get it to stretch properly, though I'm unsure how smitty tops are.
And you are right, the big soft top change happened for the 2010 model year. Windows are a different size, the brackets that connect the top to the jeep are different and as you know, the tensioning system is different. Through all of this, the Jeep itself stayed exactly the same, at least with regard to the tops.
