A pull out stopper would be great. I have the EHPro version, and my fill hole screw stripped. Before I found a replacement screw I fashioned a plug out of this product called "instamorph". It's a plastic that you can melt in not quite boiling water and shape into whatever form you want. This worked okay as a temporary fill plug, though it had drawbacks. First, it's plastic and I'm not sure how non-toxic it is. Second, it tends to get less snug over time and has a tiny bit of leaking. For ease of filling it was great. Pop it out and pop it back in. Something a little more rubbery that maintains a snug fit would be good, IMO.
Btw, I got a new fill hole screw from vaperev and everything is back to normal now.
