It's entirely possible. It's been done.
Take almost any of Brian the Brain's recent cannons. His Brass T-Bolt, Lupara, Bad to the bone... which all use hammer valve piloted QEVs for multiple shots from the same chamber.
Hotwired has also demonstrated a similar effect via a different method of partially venting the pilot volume. He can also get multiple shots from the same chamber.
I do
generally have some idea of what I'm talking about.

No, it doesn't get quite the same overall power - but he does get more shots out of one fill.
It all depends on what you're looking for in any given cannon.
