Yes in theory. No for the spam it could create.
Some people wish to remain guileless. I get 20-30 pm's a day from different people about random things.
and already I'm getting annoyed of people that want me to leave my guild and join theirs.
They don't need a button for it.
Edit:
If this idea were to be implemented, I would want a lot of restrictions on it.
Such as how many a day can one send , must be on friends list , the amount of times one cans send that invitation to the same person.
