That would certainly be the most practical way to go - my faucet is just configured so the threads are set too deep for the adapter to reach and I haven't found a properly threaded, thin-walled extension that'll fit. FWIW it's a Moen pull-out with an integrated sprayer, hence the funky configuration. Believe me, I've considered plumbing in an auxilliary cold-water feed for just this purpose!
