That's a nice idea. It lets you use GoR to promote units to more advanced forms.

A random thought: If you GoR the unit 'caterpillar' and shapechange it to 'chrysalis', which has #firstshape 'butterfly'... If the unit is attacked in the turn you turn it into 'chrysalis', does it fight as 'chrysalis' or 'butterfly'?
