Contriving unlikely edge-case scenarios whilst there's any amount of dodgy new kit out there. Brill.

Is it OK then to change the plug bottom?

My wife tried to pull a mains power adaptor for some Christmas lights out of the wall socket and in doing so actually pulled the top plastic cover off the power adaptor, exposing the transformer inside.
The contents of the power adaptor was simply a transformer, no fuse, no other components at all.
This was bought in the UK in the last few years.

I was surprised there was no mention of looking for standard numbers, considering it's the BSI...

Since not all sockets are wall mounted would not lid and base be better words than top and bottom? At least in the UK we do have a plug and socket, in France the plug for live pins is a socket for the earth.

I find the problem is often the use of the English language and the names we have used, transformer, ballast, bulb. They are not electrical words but used in electrics, in some cases incorrectly, how do we come up with an isolation transformer, what does it transform? the earthing system maybe?

Some transformers have a thermal cut out embedded in the primary winding. This is a far more effective way to prevent an overloaded transformer from catching fire than any fuse,,
