Monsterous physique, undead anatomy and shapechange

[clff rice]

So im wondering sense these spells came out after the cor rules and they thematically fit with form of the dragon and animal shapes do these spells also get folded into shapechange sense the idea is that shapechange lets you turn into pretty much anything??

By RAW no.

However it is an excellent house rule, and I believe Mr. Jacobs has said he would allow it.
