This is not the answer you are looking for. There is not an easy way to show multisig addresses (3CpowZDX3FJbfc9Q16FHeT98fp91T6Unu5) with xpub. Blockchain.info is only showing ordinary bitcoin addresses, like this: https://blockchain.info/xpub/xpub6BiVtCpG9fQPxnPmHXG8PhtzQdWC2Su4qWu6XW9tpWFYhxydCLJGrWBJZ5H6qTAHdPQ7pQhtpjiYZVZARo14qHiay2fvrX996oEP42u8wZy
