Just to throw in an experience I had of a small 'L' bracket part that snapped. There was no way I could brace it any more than I had, so I made up a batch of 5min epoxy and with a toothpick smeared and poked the glue back into the 30% fill. Then a point of weakness became very strong.
So my question is could you over dimension the parts to be joined, then remove the excess 'skin' and bond the two parts in that fashion? On a bigger area an old tooth brush could help penetrate the fill matrix quickly.  Marker indentations into the faces to be joined could help determine how much plastic to remove.
