I wouldnt do it like that. the thing is that if the hull flexes there, then you run the risk of having the epoxy crack and fall out and then you have serious problems. at the very least I would put a piece of cloth over it.
If you want to do it right then you need to grind it out and give it a good ~1:12 bevel, and lay up a few layers that get progressively larger as you go out.
If its not an area that sees a lot of wear and tear from beaching/ trailering, then you probably dont need to do the super fix, just a layer of cloth on the inside and outside.
