Why not the original ksh93?
ksh93 recently introduced the possibility to use posix_spawn() so this
should make it simple to support the lack of fork().

Well I mentioned that boostrapping AST tools from David Korn is harder than
bootstrappig my tools but it should be possible.

If VMS is close enough to POSIX, it should also be possible to compile the
original Bourne Shell (which is in the schily source kit at
ftp://ftp.berlios.de/pub/schily/)

It does require a lot more. A small note: VMS lacks the type intmax_t and
uintmax_t which is required as well as a printf() that supports %j for intmax_t
and it is required to have a scalar int64_t which is not on VMS/VAX.

Even the output format of ls and find is in the standard and if you like to
have a POSIX compliant archiver, you would ned to have "star" ;-)
