in a word, no. FreeRADIUS can help in WPA because it does the EAP methods.
with WEP you are really stuck with configuring single APs - or, in a centralised
system , configuring WEP on the central controller. 

WEP is pretty pointless too. 

If I were put into that environment I would push for Open wireless that requires
authentication before you can get anyway - ie use VPN technology. clients install
eg OpenVPN and thats configured to talk to OpenVPN server after they've authenticated.
only when they have a VPN tunnel do they get network access.  2048 bit SSL keys
are somewhat better than any form of WEP. you also dont need to go around shouting out
the WEP key to all and sundry - only valid users can authenticate. you could even use
FreeRADIUS as the OpenVPN authenticator!!  :-)
