Jkhan Grandeur (Double Cylinder) Huma Reg?

Curious how the air might move from one cylinder to the next in a situation where you have stacked cylinders as seen on the JKHan Grandeur.

Can the Huma reg be installed properly in this scenario? Not a huge fan of the double cylinder look but like the idea of the doubled air capacity. The price everyone seems to want for their Noblesse I have decided Im probably better of buying a new Thumbhole version of the .25 cal.
