Well if you don't need to pass emissions than I don't see a problem. 3V Mustang guys do it all of the time to reduce oil blow-by with either venting to atmosphere or running a catch can. So, there is a benefit.
Well, I guess if you really wanted to, you could vent the combustion gasses to the atmosphere but without a catch can or something it'd make a mess under the hood. And if you lived in an area with emissions testing, that'd be a no go.
I don't know what real benefits there are with that. Reducing blowby? These engines seal up pretty well as is.
