It's a multi-engineer-year project.  Two engineers with deep knowledge
of HotSpot could get a bare-bones port done in a year, one doing the
assembler, C1, and template interpreter, and the other doing C2.  Both
would work on the shared runtime.  To get a really performant port done
would take at least twice that, probably longer.

Anyone wanting to lead a porting project had better have plenty of
time and considerable expertise, or it'll go nowhere.  I'll be happy
to advise, cajole, and generally encourage, but it's going to take
boots on the ground.
