I don't know as much about ornithopod phylogenetics as I do about theropods,
but here are the three most recent I know of.  Note that Probactrosaurus is
always closer to hadrosaurids than Iguanodon, so you might want it as a
hadrosaurid (with your crazy stem-based Hadrosauridae :-) ), while placing
Ouranosaurus and Altirhinus as Iguanodontoidea incertae sedis.
