ah right, if you use filler i guess it'll crack due to the amount you'll be using.
so maybe fibreglass would be better... but i don't know, best to ask someone who has done theres

having it plastic welded would be the most ideal way, but if thats not an option you ban buy Isopon Bumper Fill, which as the name says, is for filling bumpers, then give it a skim of cataloy

i would say drill some small holes in the recess for the filler to go through and then smooth it off at the back too, just to give it the extra adhesion, it might not make a huge difference but for the one minute it takes its worth a try

soldering iron and some strips of the same type of plastic, make the edges of the pieces being welded into a V shape, then melt it all together
dunno how right it is but thats how i was taught and its worked fine when ive done it, although thats not a lot to be honest
