Yes, I have done this:

The changes are fairly extensive, and will require a coordinated update
of the platforms and VMMaker sources. I will be happy to help in any
way I can.

It would be best to do the updates at some time when you, John and
Ian are all available to commit the platforms updates at more or less
the same time. On the VMMaker side, I can do updates on SqueakSource,
and also provide stand-alone changes sets for updating other VMMaker
code bases (I think that the necessary change sets are all on Mantis

It goes without saying that a careful review of my changes would be
in order ;)
