RE: Decreasing HBD APR and Posting Rewards and Increasing the Importance of Hive Power (HP)

What if, for example:

HBD APR set in stone at 10% - For anyone that wants to park his money here.
From 100 to 1000 HIVE staked, HBD APR is 12% - Instant incentive to stake Hive, earn hive, or buy hive
1001-10,000 HP (Standard us plebs): HBD APR 15% - A top tier APR anywhere!
10,001 - 50,000 HP (Serious stakeholders in the blockchain) : HBD APR 18% - Even more bonus!
50,001 HP + (Big players that help to run all the circus): HBD APR 20% - Thanks for trusting us!

I guess that will be technically feasible? Not a tech person. Hope the general idea is clear. Ty
