As far as I understand Neals research paper, he's also thinking in that 
direction. 

But please see below for the timeframe.

While I think that this sounds interesting, it doesn't seem like a viable way 
to go in the Hurds current situation. 

When more and more people join in, so larger projects can be tackled and 
finished, this might become a good option, though. 

The Hurd is to a good deal a collection of servers and communication APIs 
after all, so why shouldn't these be ported to different kinds of microkernels 
(preferable with a compatibility layer of sorts, so developments can be shared 
easily). 

But that's for the time when the Hurd will have more than a handful of active 
core developers, and to reach that time, it first needs to reach other niches, 
since every journey still consists of many smaller steps - and every one of 
these steps has the chance of attracting additional developers.

Since that only depends on the question if you'll become a Hurd developer in 
your lifetime (an OS is never really finished :) ), I hope we can greet you 
here as developer some day. 

Best wishes,
