I doubt that.

There is really not that much ISA specific in an OS. VMS needs
Macro-32, Bliss, C VMS extensions etc. but they are needed by
customers anyway.

VMS already supports USB, iSCSI, FC, 10G ethernet etc..

CPU's may be limited to 64, but I don't think anyone will
want more (VMS is not for HPC).
