Had some time today so I whipped up a new aluminium timing chain plug from aluminium. Way cheaper than the $60 odd AUD the guy on eBay wanted
It's 2 pieces and when tightened provides 20% crush on the O ring expanding the O ring enough to prevent the plug falling out. I added an M3 bolt through the back to prevent it from falling apart if the front bolt is removed, in other words the back is retained and can not fall down inside the timing chain cover.

I don't have this engine and won't need it but purely curious being a mechanic nut myself, you mentioned a safety retaining screw in the back to hold the rear disc from falling out if the front hex drawing screw were to be un-threaded too far. Great idea..but how do you prevent the rear screw itself from backing out and falling in to the engine. I'm sure you have thought of that and is probably as simple as a thread lock compound on it when you first screw it in as it never needs to be touched.
Not knocking it, just a little detail I observed. It's a great little mod.

I would take a guess...
Shorter thread in the front rear part and then the screw threaded in and tightend with loctite... Shouldn't fall out at all then...
This is one of the top results when you search for the issue so I'm adding my small contribution here. I didn't like relying on an elastomer for retention of the plug. Probably not worth it honestly but it was fun. Drawing attached.
