Little idea here...

Carbon topcap with American classic tubeless valve cut to thread onto CO2 adapter

Image
Removing the Star Nut I have full clearance to fit the C02, fitting is perfect!

Image
For everyday use off race, Topeak Micro Rocket Carbon Pump fits perfect on 1/18 steertube

Co2 setup is heavier :(

My question would be how do you keep the headset tight? Fantastic idea though.

That's really clever! I'm going to make my own rendition of that now.

@deanh the top cap is just to preload the bearings before you tighten the stem on the steerer tube. It doesn't really provide much support in the sense that it keeps the stem on the steerer tube

NOTE!!! I would use this for LEFTY Forks ONLY!!!!!

Forgot to mention that! Since the lefty have the upper clamp as par of the tightening process on top of the stem, so at this point the star nut is useless after full installation.

Probably wouldn't be too difficult to modify a compression bung in order to attach the co2 cartridge to the bottom. Might not be real practical when your friends are waiting on you to change a flat, but pretty sweet idea anyway.
