Saparmurat Niyazov declares himself Khan of Bukhara, Kokand, and Khiva. Anyone who tries to tell the great Turkmenbashi that those Khanates were Uzbek vanishes.
Probably not much more implausible than the actual khanates having their royal families restored, since the Russians and Soviets both scrambled the borders in their rule there (or really what little concepts existed of borders to begin with).
