Ohai Pepperm1nts.

I'm happy for you to submit a sheet that doesn't get named until everything else is done. Hell I do it all the time.

As to stealth vessels, the simple answer would be no. Despite how long the Salarians have been at it, even they didn't invent steath craft until Normandy came along. In Novacannon, the Turian frigate Tyrus is a prototype stealth ship of a sort, but suffice to say, what very few stealth prototype ships exist are held onto very tightly by their respective governments.

As a side note, Corvettes are allowed, though they aren't hugely useful in combat, and making vessels that have stealth capability in atmosphere is perfectly feasible (and probably applies to all Salarian military craft everywhere....) but space stealth is a definite no.
