I'm afraid I can't upload things but it's only tweaks and so you're welcome to try them if you'd like to;
DM changed closed down to much less and removed tight marking. Reasoning for this is that I like the DM to stay filling the pocket as much as possible and so don't want him chasing down players. The tight marking also means he marks a player he's close to and so also means he could be pulled out of position and found he'd mark players further up the pitch then I wanted
MC removed tight marking. Same reasoning as above.
MR moved to IF support role. Instructions - Close down much more, tight marking (to track back), get further forward, roam from position, cut inside with ball, shorter passing, shoot less often, cross near post...good team work stat would be important to help track back
ML close down much more, tight marking (think it was already?)
Striker (right) DLF support. Removed tight marking, close down much less (want him to stay on man as much as possible and not chase down), move into channels, hold position, dribble more, shoot less
Striker (left) advanced forward. close down at highest, tackle harder, mark tighter (want him on DC shoulder), more direct passing, shoot less
I just prefer the movement these changes give me
I really like how you interpret / explain the tactic so will definitely try most of your changes (if not all 
) & see where it takes me.
