How about installing a through the wall skimmer? It has been done many times by others here on the forums. The only caveats are the adapter you will have to make, and cutting a hole in the side of the pool.
Search the forums for how others have done this.
I suggest this because the Intex brackets won't last more than 1 season, and for the ultraframe, you would have to buy the entire skimmer assembly, I think. I've not seen those sold separately anywhere.
