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.View attachment 1715524122
I did an engine bay for a mate and used a cap from a ford that had the bayonet style and the pcv in it aswell, I'll get back with a photo.
