Are dual techs possible?

I could have swore this had been discussed before, but I couldn't find the thread.

I want to say, it would be possible to emulate a dualtech type system, however, without doing some major coding you would have to set it up as a skill menu (like magitek or Rage) then give the characters the skill (something like that I'd suggest replacing the Def command on the battle menu in order to allow everybody the use of it without losing a command slot, technically).

At that point, the command would have to be filled with all of your dualtech/triple techs. Then you'd have to write checks that would make those skills behave properly while creating the skills. Maybe some fancy coding that would only populate the list with Techs that were usable at the time.

In short, possible, sure. Without some serious programming it would only emulate the system though. Even the emulated version would be pretty complicated. Don't let that stop you from trying, just be ready for a challenge if you attempt it.
