Just ensure that the jets blow near the intake port into the runner and from the top.
The mist won’t take turns very well.
You would have to retune at this flow level.
If you don’t go direct port, you might follow BMW’s own route and install 3 jets in the plenum chamber. The runners are pretty straight in these engines. This helps the mist actually arriving in the cylinders.

May I ask why the jets should spray from the top?
What's the downside of spraying from the bottom?
All direct port adapter plates for N54/N55 are designed to spray from the bottom because there's no space on the top.
