Staked Hive has some disparate possibilities, including the one you describe, a governance token which can only be used to vote for witnesses. There are other possibilities as well, such as a curation token, that similarly cannot be sold, nor vote for witnesses, but can cast up or down votes on content. Then there's the DHF. I can think of more, too, but they get out into the weeds a ways, and there's combinations, some of which are far more rational than others. There's also the possibility of enabling higher yields for illiquid returns than for liquid yields, or in RC's, or in specific of these tokens at different rates at the option of the owner, such as if you have gHive and want yields in cHive, or old school Hive, etc.

Not sure I like any of these tokens more than Hive as it is, TBH (although I like the possible names gHive, cHive, dHive, and rHive, for example) but it's an interesting idea. I'm not privy to your project plans, so don't have more than a vague idea what you might have in mind, but am thinking in terms of Hive. One thought that burbles up unbidden is recalling that voting in these United States used to be restricted to family men that owned property, and considering how such tokens could create separation - or dependency - between ROI and weight, governance, and content curation that could benefit the community could keep me up all night.

Thanks!
