Is this an acceptable PCV alternative?

But the suction side would be into air cleaner not into intake. This would stop that issue wouldn't it?
nope - 6 of one, half a dozen of the other. Typically the other end of the PCV hose goes just under the carb - I'm thinking if you put it up higher you'll have too little suction damn near all the time. Why are you trying to rewrite what is known and engineered to work? No port?
