Some deep sockets are already quite thin-wall, especially the multipoint drive ones. Other possibilities are a 'Jubilee' clip driver or take some suitable thin-wall tube, file a taper on a 7mm bolt and use it as a broach to make your own box spanner.

'thinning' a socket using a bench grinder might be an option, too (assuming single sockets are cheap) - mount the socket on a 1/4" hex to square adapter in an electric drill and gently apply it to the grinding wheel (making sure the socket and wheel are rotating in opposite directions). Gloves and eye protection are mandatory for this operation!

Best regards,
