Wouldn't hurt! Having those guitars in your sig wouldn't hurt either!
Best advise for Barre-ing is: Do not use the thumb strictly! Use the weight of your arm in combination with your thumb to do the fretting in order to lessen the force exerted by your thumb. Use half Barre when possible. Don't press on the frets harder than necessary for a clean sounding note. Before I knew about these techniques, my fretting hand would get real tired towards the end of the piece.
Take it at your own pace, one measure at a time if need be. Before you know it, it's under your finger tips.
