I did a post when I powered up to 30k back on Steem with some alternative suggestions for the ranks based on stake - not sure these would take off but I do like the smaller gaps between each and having more badges? Count me in!
Here's some suggestions from that post with slight modification to what I put in the original post from what you said which might be cool (although I think things are based on vests rather than HP exactly so these are ball park figures):
- 0-99 - Plankton
 - 100 - 499 - Redfish
 - 500 - 2,499 - Minnow
 - 2,500 - 4,999 - Sturgeon
 - 5,000 - 19,999 - Dolphin Mark I
 - 20,000 - 34,999 - Dolphin Mark II
 - 35,000 - 49,999 - Dolphin Mark III
 - 50,000 - 149,999 - Orca Mark I
 - 150,000 - 299,999 - Orca Mark II
 - 300,000 - 499,999 - Orca Mark III
 - 500,000+ SP - Whale
