No, that is not possible. DPMI server runs in protected mode, so it has
to be part of dosemu and a server cannot be installed from the v86 task.
It is the same reason why you can't use another 386 EMS manager under
dosemu, because the EMS manager runs in protected mode in order to use
the 386 paging unit.
Also, usually DPMI servers that are not integrated into the EMS manager
will use VCPI to enter protected mode, since the EMS manager is already
running in protected mode and provides a VCPI interface in case another
program wants protected mode. Using VCPI is unfortunately also
impossible under dosemu, not a fault of dosemu but the fault/intent of
VCPI design.
