Yes to the two first bullet items.  
The third (`pi.hole`) could be addressed by configuring [`PIHOLE_PTR`](https://docs.pi-hole.net/ftldns/configfile/#pihole_ptr) (available since [FTL v5.10.1](https://discourse.pi-hole.net/t/pi-hole-ftl-v5-10-1-web-v5-7-and-core-v5-5-released/50009)) on at least one of the machines, but wouldn't lead to immediate issues if left as is, apart from ambiguity when accessing Pi-hole's UI from the new device while both RPIs are active.

Yes, plus the equivalent for DHCPv6 and RAs, provided your router supports those IPv6 related configuration options.
