Possible to use 2 PS3 controllers on my PS4 using one crosshair?

[cmchong77]

I am playing a 4 player game (Minecraft) and already have 2 PS4 controllers. Can I use the crosshair (only have 1 unit) to convert -

two PS3 controllers

or

one PS3 controller and one keyboard?

On PS4, one PS4 controller can control just one role in the game.

And every Cross Hair will need a controller connected to it for console verification.
so you can't use one Cross Hair to convert 2 PS3 controllers.

sorry for that!
