I would agree with Tocomocho that Bulgaria is the easiest case and Georgia is least likely. Even in Bulgaria it would not be easy. "Royalist" undercurrent did exist, but school of thought directly or indirectly linking "Tsardom" with "backward past" was strong too. I guess Simeon owns his premiership in no small part to his refusal to consider being crowned. He was an ideal figure otherwise: not linked to corrupt elites, educated, wealthy, recognized internationally. Ideal "constitutional monarch", so to speak. Georgia's chances to get a king are seriously undermined by sheer numbers of Bagrationi descendant who could claim royal rights, especially after 2 centuries of intermarrying nobility without king and half-century of Soviet egalitarism (which resulted in mind-boggling number of cadet Bagrationis married to commoners). However, I suspect that, would Gamsakhurdia be a bit more sane, he could start a dynasty. After all, "father of nation" was his (almost) official title in 1991 and he had a heir.
