As in put them side-by-side? I don't think that's possible. There are other electronics you can put directly side by side, but they aren't instant like INST is.
That's INST magic. If you make an X-junction, it's treated as two separate wires crossing each other. If you make a T-junction, it's treated as one wire with a fork. Anything else (for example a rectangle of INST) is considered a single wire.
