Monaco mostly survived as because of its unsignificance, and because it was under Genoese suzerainty, that prevented it to be swalloed up as other tiny principalities.
Going for more would be the equivalent to painting yourself as a target : too important to be ignored, too weak to realistically resist; without Genoa doing anything to save them from their idiocy, as having a really small lordship attacking whoever held Provence at this time (Angevins and Capetians, historically) a new and weird form of suicide.
By the time Monaco sovereignty get acknowledge, meaning the XVIIth century, it was far to late to even hope grab 1/10 of the OP objectives.
