Don't you think, that if you need to workaround a problem with your design, 
it's better changing your design and not introducing strange things?

You say it's an easy solution, but I think it's bad since it's a solution 
ad-hoc for a problem you have with your design. If I wouldn't know anything 
about that, I couldn't understand why is needed interconnecting meters.
