Air Reg and IACV hoses

So i'm having two bungs welded to my intake hard pipe this week to finish this shit up…

one for the IACV/FICD on the driver side of the intake manifold.
one for the Air Regulator on the passenger side of the intake manifold.

I find my car likes these in our changing climates, so I choose to keep them.

My question is… If i just weld one bung, and then just split it to the other, wouldn't that have the same effect- or do they need all the air they can get from these 5/8th's hoses they use? Would having one go to the AIR reg, and then Teeing off with a fitting into the FICD be such an issue?

I don't see why not, but I figured I'd ask if anyone had issues with them.

(yes, I'm keeping them. no, I don't care if you "don't need them").
