Wouldn't that just move the problem one step farther away? The 64000
assembler produces binaries in HP 64000 relocatable format, which, as far
as I know, isn't used by any other system. The 64000 linker reads
relocatables produced by the assembler, but then it produces an HP 64000
absolute format file.
There were a few non-HP systems that would read 64000 absolute -- the Data
I/O 29B programmer comes to mind -- but I doubt that anything contemporary

I'm not aware of any. However, the 64000 used a fairly small set of
assembler directives, and they're documented in the manuals for the
processors in question. The 6801 manual is HP number 64841-90905, which is
available on Bitsavers. I don't see a Z80 manual there, though I suspect
that many of the directives would be cross-platform. It may be a
relatively simple matter to translate the 64000-specific directives into
ones for a cross-assembler that runs on contemporary hardware.
