Haha!! nice idea…
basically use an external wifi router! 
it’s another way ot thinking about it.
We have several and we use them on the go, so it could work.
But what I am afraid is that we still have to start them up by pressing some buttons, and sometimes we have to operate on them (reboot… check connection etc). So they could not really be integrated into a Raspberry since they don’t allow for a control interface.
But it’s an idea nonetheless. Thanks for the change of perspective
