I'd overbore the holes, coat the wood with neat epoxy (no thickener) using a cotton swab or equivalent then fill with epoxy thickened with microfibers. Redrill and use new screws same size as the original.
I don't like using thickened epoxy without coating with neat epoxy first. You don't get as good a bond and you may leave gaps. Dennis C.
