The only problem I would have with that design is that it doesn't sit flush with the wall when in use like BS1363 and some italian plugs.
Could you make it flat?
Why round pins? Don't they produce all kinds of spring/contact problems?
Wouldn't blades or at least squared pins like UK plugs make the socket contacts easier to manufacture?
The chances of CENELEC pushing for a standardised plug is pretty slim, however, there must be some scope for applience connectors that are better than the current IEC ones?
I don't like IEC connectors for a number of reasons:
Generally unshuttered
Prone to overheating and sparking.
and the figure of 8 connectors aren't polarised.
You would need a keyed plug system:
1 for heavy appliences up to 13/16 amps.
1 for lighter appliences say 5-10amps
and one for small appliences like sound equipment, TVs, VCRs etc etc
At least if there was a standard, safe, universally accepted system it would mean that all you'd have to do is change the plugs!
Alternatively..
What about this scenario:
Similar connector system, but have a European standard applience connector fitted to every applience instead of a plug.
Plugs with a small trailing cable with an appropriate receptical could be sold in each country to suit national standards.
If the design was neat enough, rubust and safe it could be used long term eventually becomming the pan european plug.
When connected to the national plug a screw could be inserted to lock the connector together.
