I doubt that you will get that concealed handgun permit should you relate this plan during the required classes. You might also be interested to know that a friend of mine who has this license firmly believes that he was given the third degree by the police when stopped for a minor traffic ticket. It apparantly pops up on their computer when they run your DL or plates.
I am a gun owner, also Texan, and sometime hunter, but not a staunch self-defense by handgun advocate. I sometimes wonder if the concealed-carry thing is a sort of subtle "gun registration" method or could be used as such in the future...
Anyway, doesn't Dallas already make enough Anti-Gun publicity as it is? Think about it, Grassy Knoll, coach Switzer arrested at DFW with a 357 is his carry-on, and now our rookie free safety shot twice in two years within the metroplex...once in a drive-by, and before outside a "club".
Seriously, my concern with this (and I hope you are just letting off some harmless steam) is that it could give the JW elders "ammunition" to claim you assaulted or threatened them, or tell everybody who will listen that "apostates are crazy"...
