You're going to have to cut it really short. Most of the delay element is burned while an APCP motor is burning. What's left burns at something like 1/32" per second so you're going to have a thin piece of rubbery stuff that's going to need a bulkhead to keep it from blowing out too soon. What you end up with may work but I think Carl's DECAP system is a lot simpler.
