Boxing in or covering over what might be a diffuser??

I have a big open space on the left side of the rear bumper. You could stick a bread box in that hole!


I didn't think too much about it before I removed the mud flaps. (This is before the mud flat was deleted).
That large member in the center (with the holes) is where a trailer hitch would mount.


Before:



After:

You can see the backs of those yellow mounting plugs on the top photo..

Before the flap deletion, the path between the left rear wheel and the void was blocked somewhat.
Now, it's wide open. It seems like air coming off the wheel is going to drive right into the void..

When I first saw the 'after' view, I had a strong urge replace the flap with a mini-flap that didn't extend down below the bottom of the low pointy part of the rear bumper. (Just below the bottom clip-nut).

I'm thinking of 3 choices:

1. Add a small (short) coroplas block where the old flap was screwed in.

2. Do number 1 and add a coroplas cover over the void, decreasing it's depth.

3. Do nothing at all and let the air go where it wants to, since the Void is really a diffuser..?.

Thanks for any comments.
