He didn't use a doubleneck tele on HAND purely because Bobby Bandiera was playing the solo for that track. The song requires a capo at the first fret on the top neck for the verses/chorus, and uses a standard open E tuning for the bottom neck for which Richie usually plays the solo. Since Bandiera played the solo, Richie didn't need a doubleneck for the song.

And the reason there was no doubleneck Taylor acoustic for 'Wanted' was because Richie has a new toy - it's a guitarist's curse that you can never own enough guitars so why play an old one when you've recently gone out and bought a nice shiny new one!?!?

There ya go!
