Sure, but who's going to write the driver in the first place? Linux's "millions of lines of code" are a really underappreciated asset, there's tons of obscure hardware that is no longer supported by any other actively maintained OS.

I also don't see how we could transition to a microkernel, indeed.

The very first "hypervisors" were actually microkernels that ran Linux as a guest. This was done with Mach on PowerPC/Mac systems, and also the L4 microkernel. That's one way.
The only downside of course, is that you don't get the isolation benefits of the microkernel for anything depending on the Linux kernel process.
