Larry I like your solution. Just a comment. I think that you should use a twist and lock type of inlet so you don't take the risk of the power cord getting disconnected by accident. Do you thing that putting two of those in a dual gang box will be a problem?. I'm doing a job right now where I will need to get 3 in a dual gang version and like two in a single gang. See if it is feasible to have them done and also the twist and lock option and I'll be your first client.
