Your goal for the additional equipment should be: - 3,700+ Battle Power (the potency scaling for Mobile Cannon stops there.) - 100% potency floor - As much base ATK as possible

Things that do not work on Mobile Cannon are: - potency multipliers - weapon potentials - preset skills ("fixas") - anything else that wasn't already mentioned in the previous post As an exception, weapon element does only work in the Mobile Cannon phase of Dark Falz Aegis.
