I use something similar to fill 3 corny's from one sanke at one time in tandem/parallel.
I would buy that from you if you didn't want it. The fitting I use is an aluminum pneumatic fitting. The only non-stainless bit of kit I have and the only thing threaded post boil kettle too, so I just make sure to sanitize real good.
Here's a vid. Obviously I didn't stick the dismount, so be gentle! I changed my method after I made this vid. My theory is: Every output is at the same angle and there isn't one straight and two 90* (like there would be in a cross). After the receiving kegs, there is a 3 into 1 gas manifold attached to my spunding adjustable pressure relief valve. So every vessel fills at the same rate as if you were just counterpressure filling one alone.
As you can see in the vid, I was right as I'm getting within about a couple cups margin of error, but I'm no fluid dynamicist and wasn't willing to buy a cross to try it. That may work too...
I think that fitting would work well for this purpose. I've seen breweries do this with several kegs off of the bright tank.
And a pic of the fitting from McMaster (there's one npt on the other side):
