Are you suggesting an interest bearing account for Hive (similar to what has been previously proposed for HBD)? It's certainly possible to implement, although it's non-trivial and would be a new source of inflation, of course.

But on a macroeconomic level, I'm not sure what the justification would be though, unless it's just a way to get Hive out of circulation in order to increase scarcity. Generally, I'm not in favor of such mechanisms.
