Hello Tzoli,
sorry for being late, but I finally got some good news for you.
In July I've sent a request to the Ufficio Storico della Marina Militare (which you've mentioned last time) forwarding your request plus some questions of mine for good measure. Well, two months went past without a thing happening. Then a couple of weeks ago one Frigate Captain working at the Ufficio Storico finally got in touch with me; his response basically was: we've been closed due to Covid so far, we're just starting to reopen, you can forward you request again to the Ufficio Storico so they can fix an appointment for the stuff you've asked for.
Apparently they've got very little material scanned and/or digitized, so very likely the plans you're looking for (if they're actually there, it didn't say), are paper only.
So, what I would suggest you is the following: send your request to the following address:
ufficiostorico@marina.difesa.it
And ask me if they actually got what you're looking for. Then you can agree for an appointment to see and hopefully either ask for or get the digitized copies to work on, unfortunately they will only receive on appointment right now, and you must contact them first and agree about a date. You have to do it yourself because it is specified in their own website they won't take requests on behalf of third parties.
So now that we seem to know why there was no answer so far, well now it (hopefully) should be all working regularly. The time they take to answer every single one of your emails is still measured in geological ages but they should give you a response within a couple of weeks (again, hopefully).
I think you should ask if they actually have what you're looking for first, and only after ask whether or not they can provide any digital copies or what, although I have a feeling they will still ask you to come over for whatever reason. Unfortunately going to Rome is not easy for neither of us (and yes, I still have an unresolved question with them, but I can wait for that, I've already got too much on my hands right now).
They should be able to provide more info on that.
Hope this had been useful
