Edelbrock Crankcase Ventilation Hose Connection to PCV breather

Another question if possible.

I’m unsure of this, but can I drive the grommet for the PCV valve into the hole for the breather (see attached picture). I’ve been under the impression that the grommet wouldn’t cover the surface area left by the slots for the tangs. If the PCV grommet could be driven into the present hole without any air leaks then my problem is solved.56BE9218-B5F0-4061-8819-21D91C07ACFE.jpeg
