The fact that spells like megamorphosis exist suggests to me that the natural changes are focused on things like making sure her sex organs are a perfect fit for yours, that she finds your mana the tastiest, etc. However, we are lacking in confirmation that the changes are limited to that.

That said, it certainly seems that at the very least major physical changes usually don't happen simply from finding a husband and adapting to him. That is if they did I think we'd get some direct references to it by now.
