Well, if it is just under 18 1/2", it would probably be over 18" and that is good enough, as is the 27" overall. Someone knew the Federal law and made sure not to violate it.
IMHO, trying to make it into a full length shotgun would cost way more than it is worth, even if Rossi parts were available. You might try www.gunpartscorp.com but I wouldn't hold out much hope. To have a stockmaker do a stock and a barrel outfit make barrels would cost well into the thousands.
Garcia has been out of business for years, and Rossi has been taken over by Taurus. If you need parts, try contacting Taurus.
