Snorkel into cowl vent?

I have a 89YJ carb. I-6 I just did the Nutter bypass which gave me alot more room along the firewall has anyone moved there air intake to the cowl vent through the firewall? I took off the grill and screen that covers the cowl vent and noticed there is a plastic airbox to direct fresh air. I was thinking that I could drill a 2 1/2" hole with a hole saw as high as I could through the firewall behind the valve cover in a flat area then use some PVC fittings and a short piece of 2 1/2" plastic flexable hose to make the connection from firewall to stock air cleaner.
Since I did the Nutter Bypass I also welded all the holes shut on the stock air filter housing and found that I could also turn the base facing the rear of the engine so only a short piece of hose will be needed from firewall to air filter housing.
While at Home Depot I also seen some 21/2" pvc pipe covers look like dryer vent cover only smaller that could be put into cowl vent area on the end of the pvc fitting that will be installed to keep water from entering air intake as easy.
So has anyone done this on there carbed YJ? Or anyone have any better ideas? And please don't say get a ARB snorkel it would not last long on the trails I ride and I could by a front locker with the money I'll save .
Thank You, Jeff

I did do a search only 2 things come up and neither one of them gave any detail or how well it ended up working. I'm mostly concerned with keeping water from entering the pvc hose trough the cowl vent. I did have a pvc hose siliconed to the air filter housing and routed right up to the firewall with a little space for air but still would get a little water in the air filter housing.
