Is it possible to create a platform similar to Steemit Inc, running on the same steem blockchain, but with different rules?

I love the basic steemit.com idea and I love the community I have interacted with on it. The numerical skewing of the reward system by too few owning too much robs well intended bloggers and those who follow them from any monetary incentive sponsoring them.

This is sad. It seems to be still possible for any poster of quality content to build a healthy following and to achieve at least some recognition, albeit without significant reward. Some have to earn their daily meals with the time they spend writing really quality posts. If quality authors cannot support themselves writing articles specifically for posting here, the system fails them.
Simple as that.
