Would this path work:
1. Only one localbtc to buy coins.
2. Send from localbtc to bc.info Wallets A and B
3. b.info Wallet A sends to Electrum A
4. b.info Wallet B sends to Electrum B
Would electrum A and B still have linkage due to the original localbtc wallet?
Yes, albeit a weaker one since there's an intermediate transaction in between.
