That happened in the late 80's / early 90's and it was called Plan 9. And there was a reason it failed to fill its intended role:

  [I]t looks like Plan 9 failed simply because it fell short of being a compelling enough improvement on Unix to displace its ancestor. Compared to Plan 9, Unix creaks and clanks and has obvious rust spots, but it gets the job done well enough to hold its position. There is a lesson here for ambitious system architects: the most dangerous enemy of a better solution is an existing codebase that is just good enough.

Then you don't need to worry about "looking forward" to replace any of those things.

Plan 9 failed because Bell Labs management did not care enough, and eventually placed the team into the Inferno project to try fight against Sun and Java, that is why.

The lesson is that if you want a project to succeed ensure management is on your side for the long road.

I still need to care, because the final decision what to use is not always on my table.

The Inferno project was around a year of disruption. But yes, the whole Labs management failure plays a part too.
