The only thing I like to do with Hogs is to drastically reduce the dihedral. It was as you maybe know made for the early radios, and needed more stability than is required these days.

I used Solartex and paint, plus in them days I built 'em pretty solid. The model in the pic was stuck one foot deep in soft clay, with no damage. Bit of a job to get all the mud out of the cowl though.
Later model had flaps, and a cowl much like a Ryan PT-22. Those cowls used to be much in demand. One went to Terrace, B.C.
The flaps on a porky Hog is a lot of fun. You come in for landing in pretty well a dive, full flaps, and it settles beautifully.
Hah, worked at last! (the picture) Live and learn.
