Can I use a physical keyboard as a game controller?

I have a phone with a physical keyboard (F(x) Tec Pro1 X). I would like to map that keyboard to game controller inputs so I can use it to play Android games that support controllers. Unfortunately I can only find Apps that do the opposite - mapping game controllers to keyboards. Is there a way (specific App, Tasker scripting etc.) to use a physical keyboard as a game controller on Android?
