Sometimes you don't need to redo everything from scratch to change things.
There are a number of problems in scientific publishing. Two big ones are:
1) Distribution hurdles and paywalls imposed by rent seeking journals - who knows how much this has prevented innovation and scientific advancement in the last 20 years
2) Easily replicating experiments / easily verifying accuracy and significance of results - this is related to for instance making data used in research more easily accessible and making it easier to spot p-value hacking
Fixing these might not require a completely new format for papers. Or it could. I can envision solutions both ways.
I really like what the folks from Fermat's Library have been doing. They have been developing tools that are actually useful at the present time and push us in the right direction. I use their arXiv chrome extension https://fermatslibrary.com/librarian all the time for extracting references and bibtex. At the same time they are playing with entirely new concepts - they just posted a neat article on medium about a new unit for academic publishing https://medium.com/@fermatslibrary/a-new-unit-of-academic-pu...
