How exactly would be encrypting data here? WEP is only defined in IEEE
802.11 (i.e., for wireless networks) and it should not really be used
for any new purpose due to major security problems.

Sure there is, but something would need to specify how the key is to be
derived and what mechanism would be used to encrypt the data packets.
Before those parts are resolved, there is not much point in trying to
get wpa_supplicant to do something.
