Dean:

That all depends on what the 12" siphon system pipe is made from, and if the 12" pipe in front of the butterfly valve is full of water when the valve is shut.

1/4" wall or thicker steel pipe? Maybe. If it was mine, I'd open the valve, drain all the water out. Cut a hole where you want the hose bib. Weld on a bung that is threaded for the hose bib. Install bib, close butterfly valve.

PVC? Maybe. I'd feel a lot better cutting the butterfly valve out glueing in a "T" and necking down the one end of the "T" to accept a hose bib. You can glue the butterfly valve back on to the other side of the "T"

Any other material, I doubt it.
