If I wanted to accumulate some BTC anonymously and just hold it
would this work?
Buy XMR on a KYC exchange.
Withdraw it to a Monero wallet connected by TOR or VPN
Transfer to a second Monero wallet connected by TOR or VPN
Send XMR to a non KYC exchange and buy BTC
Withdraw to BTC wallet connected by TOR
Any corrections, suggestions, or better ideas?
Yes. Find somebody with Bitcoin in real life. Offer to pay them cash for it. Done deal basically. Or you could find somebody on peer to peer. I believe that website is still up and going. Lastly, you could facilitate a deal on here. More risky, but somebody will probably send you funds if you e-transfer them.
