my initial idea was to just dump specific info, but like you said it is a pain trying to find what you want,
then I looked into karmetasploit and thought why dont we do this
create a fake ap using airbase-ng, user is redirected to exploitable page and the exploits run in iframes, we dump the whole registry.
and then search the registry in our own time, we can be prepared next time by having the wpa keys, and as you said all sorts of other vital information
now what we need is a single universal way of uploading a payload, my guess would be to create something on the redirected page
