Here are my thoughts, as promised. Take a look at these two images that show the passes of my DLP Goretzka and the average positional heat map of the entire team.

I think the main problems with this tactic in getting the regista involved are as follows:
1.) Tactic very narrow up top. A regista needs to be able to pass the ball long, short, forwards, backwards, left, right. As it stands right now, the regista has a mass of bodies in front of him, so many in fact, that there are no discernable options. The wingers need to stay wider, work the channels, and spread the play. I would do this not by expanding the Width slider, but by setting the IF's wideplay to "Move into Channels". And limiting the amount they swap positions.
2.) DLP mentality too attacking while centre backs too defensive. A good regista should almost walk the ball off the centre-backs, sitting right in between them for most of the play to always give himself options.
3.) Tempo too high. It may not seem that high, but the slower the better. The slower the tempo, the less impetus the players have for getting the ball forward to the front line; ergo, they will pass to the playmaker more often.
4.) Your centre midfielders are so close together they could almost kiss. It's a waste of a man in the centre of the park and instead of having 2 options to pass to in front of the regista, they're likely to both be marked out of the game by one person and there'll be no one for your regista to pass to. You don't need these guys swapping positions and roaming, they aren't where they should be when needed. Just look how many passes through the middle are cut out.
5.) Don't be afraid to adopt a deeper line, pushing up allows little room for freedom of passing range.
