Is this correct/usable (opamp V offset compensation)?

Is something like the circuit bellow correct/usable for compensating the offset voltage of a jelly bean opamp?

I don't think so. You are never going to have two completely identical opamps, so the offsets aren't really going to cancel each other out.
