Is there any technical problem to add in additional HS-422 Servos?

I would like to modify HexCrawler by adding in 2 more HS-422 servos, so the Hexcrawler will have 14 HS-422 servos.
Do you think existing combination of BS2 controller, LCD AppMod,·BoE·still can·be·configured to make·all 14·HS-422 servos to move at the same time?
Is it necessary to increase·the power· to support movements of all 14 HS-422 servos?

    You probably won't need to increase the power but there has to be something controlling the servos other than the bs2. You will need to make sure this can handle the extra servo control lines.

    You may need Parallax servo controller board. Current adds up. Does the stamp get warm? I have a used quadrabot I got off an engineering student (9 servos). I haven't fired it up yet but was designed with a servo conttroller along with the LCD app mod. The servo controller takes a load off the stamp and is controlled with a serial line. It has a 7.2v nicad to power the motors. Just learning the boe bot for now.
