In one of my occasional ventures into writing Latin poetry, the topic turned to combatting poaching by weekend scuba divers in a shellfish fishing area: the fishermen's patrol craft "e furtu cancror(um) alienor(um) // inhibet" with two elisions including a hypermeter: "stops [them] from theft of other people's crabs": as the two elided words were interrupted, so the shellfish poaching was interrupted. Is this an acceptable form? ('//' means end of line.)
I read that a space between words after 4½ feet (in a non-spondaic line) sounds awkward, but here the first elision makes sure that the first syllables of the 5th and 6th feet are both stressed.
