I wouldn't worry about it too much. No matter what you do either boot doesnt crit or dk doesnt apply debuff after pb ends. Nothing can be done about it but ir should be up which gives boot a higher chance to still crit. So even if you were somehow able to boot during pb (like my double monk party opener where I move twin into dk spot and then boot where I normally twin), leaving pb would require you to hit another boot without a form.
