I have historically used the system you mention, drilling a hole in the chin guard at mouth level, and running a short piece of tube, with bite valve one side and cools suit quick disconnect fitting on the other side.
The length of the tube should be enough to push the bite guard into your mouth before the quick disconnect stops the motion. Don't have my helmet here but it has to around 4-5" on the Arai GP5. Make sure you put your helmet on first and mark where the hole needs to be as it needs to be a straight shot to the mouth for the tube. Remove the chin padding and cloth and tape the helmet before drilling so you don't scratch it if the drill bit wanders. Hole diameter is just 1/32" larger than the tube diameter. Bite guard needs to be zip tied to the tube so that a forceful removal doesn't dislodge the valve from the tube. Longacre bottle feeds the system.
The only drink mixture that I have ever used that has helped to reduce my chronic cramping is Cytomax made by Muscle Milk.
I am now using a Stilo helmet with the built in hydration system, but the first time I used it I almost drowned at Sebring as I was unable to get the bite guard out of my mouth and as we bounced through Turn 17, my jaw was closing on the bite valve, and the drink was just pouring down my throat, all the while I was holding my breath through that total commitment turn. I have changed the bite guard to a 90 degree swivel system and I have got the drowning somewhat beat!
