And another service for the privileges.

A lot is possible if one is willing to put enough effort into it.

But I don't see any point.

For this model you will end up with x10 code doing emulation compared
to the original VMS code.

And performance will likely suck. You are really proposing a
microkernel design - a full size monolithic Linux kernel and
VMS services implemented as user mode services.
