I think you should email AH Supplies for their take.
You can in theory fit a retrofit kit into any canopy that has room, but I can see problems trying to attach a kit to the plastic hoods ... there is no where you can screw the parts to .... It would be pretty unlikely to have the kit fitting your old light exactly so that you can use existing mounting points. But do check with the kit maker to see if they offer a solution.
