Geez, that is certainly timely. We just spent how much time talking about this very issue!

I just did a very similar mod, that achieved the same results.

I ended up cutting and reverse plug down, and then welding up the hole, and cut a grove into the top to use a flatblade screwdrive with it.

I just then used some ultrablack to seal it in as i didnt have any locktite available at the time.
