You know, if you could come up with a better way to implement it, you could become a billionaire. But maybe you already are, everything is possible on HN.
Go to XRPL.org its literally that and it exists since like 2013, It whole goal back then was to make a better bitcoin.
Plenty other projects have adapted the concept or even forked the code.
The core team behind this back when it was named opencoin are without a doubt millionaires now and some even billionaires. So you are right but it way way to late now.
Not to says that there could not be a even better solutions. But its already several thousand times better if you compare raw metrics like speed/TPS/energy usage etc. an even better solution would likely not make that much of a difference again.
