That's a GREAT IDEA!

I think the biggest problem with the Johnson Controls Duralast 49-DL is that the vent hose 'might' get pinched (which is likely why it's never listed as a direct 1:1 replacement in the 'official' battery searches).

So, anything we do to alleviate that pinching, is something we must report so that OTHERS don't end up with exploded batteries due to ignorance of these tricks.

Luckily, it just so happens that I don't think I gave Autozone my old red battery terminal cover. So, I'll try out your suggestion and post a picture if it works well!

In addition, if it works, we need to get the word out so that others know not to return the red plastic battery cap cover!
Here's a pic of the OE cap that covers the positive battery cover...installed on a Duralast 49 DL:
