But as I said, I think you can alter their shooting tendencies and risky passes via PIs? Don't have the game open right now.
Most of the AML/R roles involve dribbling often. If you don't want that, then you should really then look to either drop them back a strata or use central AMs.
Support Advanced Playmaker is probably the worst of the roles you could have chosen if you also expect them to make runs and share goal scoring duties. They're not aggressive enough. The Attack duty version is maybe worth a shot to see if it's what you want, but again, they will be playmakers. They'll receive the ball more and they'll look to supply rather than score for the most part.
Maybe that's the main problem here. Variation is good, don't forget.
Remember what you're asking your players right now. You're asking all 3 midfielders to remain narrow and sit next to each other. That's making it dead easy to defend. Especially when 2 of the 3 won't really be looking to make runs either.

I don't understand why you have Retain Possession though? You didn't select it to reduce through balls, because you added that back with Pass Into Space and you didn't select it for the Shorter Passing, because you already have Play Out of Defence and Shorter Passing.
You can change the shooting tendencies and risky passes, but the dribble more and cut inside PIs are there by default and cannot be removed. So an inside forward will still do the same thing.
If I drop the wide AMs back a strata then I will not be able to create the diamond that I want.Moving them central leads to the problem of them getting in each others way.
I have Retain Possession because I want my team to hold on to the ball when there are no passing options instead of giving it away, and also because I like my team to have the most of the ball.
