An Idea on Remote Node Privacy for Wallets

I know, everyone should run their own node. And I do run one. But we won't convince everybody to do so, so we might as well help the less technical people to get the best privacy they can. I had an idea today on improving the privacy of wallets using remote nodes and Tor and would like to hear some opinions on it or if this already exists.

So here we go: Consider your typical wallet that connects to remote nodes to sync its addresses and to publish transactions.

A wallet like this could use one remote node per address that it checks, i.e. a new remote node for each address. Not perfect, but definetely an improvement, especially if many people ran this kind of wallet. This prevents the remote node operator from easily knowing that all addresses belong to one and the same wallet.

The wallet may additionally change its Tor-IP between each new connection it makes. This protects somewhat from different node-operators cooperating in data collection.

The wallet may additionally add random time delays between the connections. This would come at the cost of longer sync times (e.g 1 hour or 1 day for checking all addresses) but would additionally enhance privacy for the paranoid user, that isn't in a hurry.
