Answer 1

Yes, absolutely. You can use dumpprivkey and importprivkey to transfer private keys from one node's wallet to another. The only caveat is that you should not generate transactions from the same address in multiple nodes simultaneously, unless you are manually managing transaction inputs (and using createrawtransaction) because this will likely lead to clashes. But you can certainly use this setup for a failover scenario.
