See my post above.Look around. You will find different ideas/plugs for ‘fix’.
One type that has been available for years, is a plug with a drain valve built in. And it has a small ‘pipestub’ to attach a rubber drain tube.
Can be shut off/on easily and addresses the messy problem of oil changing. This plug just stays in place.
I can’t do pic here. But a search should find it.
I bet you could easily weld or braze an oil drain plug bung onto your present pan.
This one looks good as it has a low profile.

Here's a couple ideas, ones we've done most recently on a number of Flathead pans. Relatively easy!
Thanks, Gary in N.Y.
P.S. I may have a couple bushings we fabricated here in stock still, these require welding however to install! You can use a "conventional" drain plug after the fix.
I never have any problem, I do wear latex exam gloves but never had a mess or any splashing. How far does the oil drop before it hits your container? When the plug gets close to the last threads unscrew it quickly and hang on to it. You can put blocks under your catch pan so it is closer to the oil pan.
. Also there is an advantage of having the larger hole, you can stick your finger in there for a good feel around.
