Aww, this was my prompt, thanks for reposting it! And word, if someone wants to take a crack at it feel free. If only because the remaining Auditore kids need more (innocent) fun times together. Especially considering in AC:R, Ezio seems to write Claudia every chance he gets, including about more personal things (like his mention of Sofia). Not to mention, in Embers, it's implied Claudia lives close, considering Sofia takes the kids to see her for the day.
