don't want energy efficiency
Actually we, those who have seen
many coins developed during the years, have noticed that if a coin doesn't "waste electricity", its price will rather soon go down never to recover.
So I guess that most of those answering are just afraid to lose money, not "bitcoin cultists".
So my advice is to make your own coin with this idea and see how it goes, but I must warn you (if you didn't already know) that it may be a wasted effort.
You can make your own fork too instead of coin, but then you may face the hate of some (especially if you'll use the word Bitcoin in your fork's name) and some of those having bitcoin will probably dump their fork-coins as soon as you'll give them the opportunity.
Of course, you are free to try.
PS. You should start with reading more about PoW and PoS, you seem to have quite some misconceptions here and there.
