[MENTION=1173]Hammersticks[/MENTION] It would be mostly possible, but would take some work. For each desired hand signal command, you need the corresponding code. Examples:
Stop: {doStop x} forEach units group player;
Rally Up: {x doFollow player} forEach units group player;
Get down: {_x setUnitPos "Down"} forEach units group player;
Etc.
Move left/right a little more complex, as you need to calculate a position left or right to command units to move to.
We would have to look at the PF hand gesture function code to see if they raise an event when using the signal. If they raise specific events or set hand signal specific variables, then we can have code to detect that and issue the corresponding commands. If their code does not raise events or set variables we can sense, then we would be stuck with making our Action Menus that playAction the hand gesture, and execute the commands (that would suck).
Here's all the hand gesture actions:
