I like this idea for it is simple and intuitive. What I don't like are 
methods that take objects because they have no compile-time type 
checking. My suggestion would be to consider generics like so:

public <L, R> and(L lhs, R rhs)

I didn't think this through completely but do you think this could work?

Looks reasonable to me, go ahead.
