We would need to do some work to update hive codebase ro work with the former eosio chains but there is already an alliance between hive and telos and an alliance wuth eos telis wax and ux
Combine the two and add bitshares golos and steem and well have a combined force of USERS and DEVELOPERS across Bitshares Steem Golos EOS WAX Telos Hive and UX (they were created in that order I believe)
