In case, anyone else wanted to convert their kickstarter Pico S to a pro, using their provided regulator, I found a site selling what i built. I guess it's similar to what JRB03 did as well.
I wanted the flexibility of using larger bottles. (24oz paintball in my case), and 16g disposable as well.
Plus, I wanted the gas line to be on a hose, not fixed on the regulator, so it won't strain due to the weight of the paintball bottle.
The weekend brewer sells this:
https://www.theweekendbrewer.com/collections/kits/products/co2-injection-system-for-paintball-tanks, which is what I did from the one that came with the pico.
First, I replaced the out port of the regulator with this:

I added the paintball adapter :

And the hose, I made it so the length of the tube was long enough to have the bottle site next to the keg in my fridge, while not too long. Hose for gaz, and 2 swivel nut (barbed) with 1/4" (inside diameter) male flare (MFL) connectors. Get the ball lock connector with MFL connector, and all you have to do is connect the hose. Should you want something shorter, replace the out port with this female adapter:
https://www.williamsbrewing.com/MINI-REGULATOR-CHECK-VALVE-FEMALE-FLARE-OUTLET-P3962.aspx
and you can connect the regulator directly to the ball lock connector.
One important notice, to get a hermetic fit, a washer inside the swivel nut connectors is recommended.
This one comes with it:
https://www.williamsbrewing.com/14-TUBING-BARBED-ADAPTER-P110.aspx
and often your homebrew store should carry them. Beats waking up to an empty tank and flat beer!
And if you don't care to be able to remove the hose, you can save a bit further by using barbed ball lock connector, and a barbed 1/4" MFL to 1/8" NPT on the hose.

Cheers.
PS: There's nothing wrong with the Pro kit conversion that PicoBrew sells by the way. I wanted something more flexible. Since I carb with paintball bottles at home, don't have a kegerator, just a fridge, and preferred to use 16g bottles or paintball bottles instead of the more expensive 74g bottles... it made more sense to me to build it and buy kegs seperatly.
