Well and there also is the chance that the earlier independent kingdom of Croatia survives.
However in all these medieval cases, except for the Dalmatian coast, expanding south and southeast is the most likely area for direct Croatian expansion; however there they probably will also meet resistance, but it's relatively speaking the weakest neighbouring state/area, since their other neighbouring realms were Hungary and the Holy Roman Empire. However a king of Croatia could end inheriting Hungarian and/or HRE fiefs, but these will be held in personal union.
IMO, no. The opponents were too strong. Even survival of independent Croatian Kingdom is a big thing.
