Sorry, Bob
Volcanic craters are characterised by the presence of effusive volcanic rock. Although Mars has PLENTY of volcanoes and plenty of volcanic rock, the majority of surface craters are NOT associated with lava flows, ash deposits, or other volcanic products.
You're on to a loser if you use mere morphology to support a re-run of the 1950's Lunar cratering debate. That debate was clearly won by the impact proponents, for many good reasons.
For the morphology of Victoria crater, I would be addressing the role of aeolian erosion over hundreds or thousands of millions of years - that isn't in any way a "young" crater and much of the "expected" morphology of an impact crater has been modified by erosion and collapse of its rim.
