Possibly... The other thing that comes to mind concerning vac tubes is velocity. The smaller the tube the quicker that air volume will want to move as the force increases.
You can slow things down by increasing orifice and line size and/or increase the number of lines that are pulling vac. The slower all of that air moves, the less oil vapor will be picked up and allowed to escape through your breathers.
I might look into a way to slow that air down to keep the oil vapor inside of the catch can.
