BIP47 is great but solves a different problem, still need to use coinjoin.

Agreed, i always whirlpool any deposit. PayNym is great for repeated payments without the need to reveal any address.
Sounds like you wanna double dip. Bitcoins value and privacy. Bitcoin was never made to be private while Monero's(XMR) privacy technology is similar to CoinJoin, in that it uses ring signatures to mix the spender's signature with the signatures of other users to make tracing addresses nearly impossible...
What are your thoughts on XMR, other than "its not bitcoin"?
Samourai tools are the best privacy tools in bitcoin, no silver bullets but a range of options that work today
they will soon offer atomic swaps with monero which adds more options
monero has utility, i am not anti
Monero has several layers of privacy that are all by default (important):
Ring Signatures obfuscate senders
Confidential Transactions hide amounts
Stealth Addresses hide recievers
Dandelion++ hides IP
Here are some major differences between coinjoins and ring signatures:
