Since your enganche (Ganso as AP) will play on the center of the pitch sidelined by 2 other AMC's, it might not be just as easy to make them go wide to whichever side the ball goes.
But if roam from position isn't delivering what you want, you may try other PI's such as move into channels perhaps? You can also try to remove the Counter instruction and go for Hold Shape - besides being more suitable to Diniz approach of positional play it would be hard for you to understand the issues with the positioning of your AMC with counter + roam from position ticked. It will be easy to start simple and building from there than to have those 2 instructions (TI + PI) ON and wondering about the issues you see happening on the pitch.
Regarding the defensive shape, It would be easy to defend in a 442 if you were using that shape as base on some sort of lopsided 442/4411 might also work...
