Doesn't look good based on the Service Manual:

8J-2 Instrument Cluster
The instrument cluster (Fig. 1) is referred to as a
Electro-Mechanical Instrument Cluster (EMIC).
Some of the features it controls are the gauges
(except fuel), courtesy lamps, chime control, Daytime
Running Lamps (DRL) and cluster self diagnostics.
The cluster sends and receives messages via the Programmable
Communication Interface (PCI) data bus
circuit (J1850). All instrument cluster indicators (Airbag,
Seatbelt, etc.) are LED’s and are not replaceable,
with the exception of the high beam indicator
which is a bulb. The gauges are not serviced individually,
thereby requiring complete replacement of the
cluster if one indicator or gauge becomes defective.
OPERATION
The instrument cluster controls the courtesy
lamps. It receives and sends messages to other modules
via the PCI (J1850) bus circuit. It controls all
the instrument illumination and the chime is also an
integral part of the cluster.
All gauges are the analog type. When the ignition
switch is moved to the OFF position, the cluster
drives each gauge to its lowest position. The individual
gauges are not serviceable and require complete
replacement of the cluster if one or more gauges are
inoperable.

The drawings don't show bulbs accessible from the rear of the instrument cluster and there are also the following warnings:

CAUTION: DO NOT turn cluster upside down for
longer than 30 minutes (preferably NEVER). This
can result in dampening fluid within the gauge
pointer assembly to leak causing permanent damage
to the instrument cluster gauges.
DO NOT expose the instrument cluster to direct
sunlight for extended periods of time. Any overexposure
to direct sunlight permanently warps the
internal mask of the instrument cluster, causing the
pointers to stick. It is acceptable to store the instrument
cluster on the floor of the vehicle, gauges facing
up, out of direct sunlight.
DO NOT do an electrical “HOT SWAP” when replacing
or testing clusters. Ensure that the ignition is
OFF with the M1 fuse removed, or the battery negative
cable is disconnected. Partial mating of the
cluster connector circuits can damage and/or
destroy the cluster microprocessor if power is
available.
DO NOT swap clusters between vehicles. The
instrument cluster has learned information stored in
its microprocessor for Airbags, Anti-Lock Brakes,
Traction Control, Cruise, and Smart Key Immobilizer.
Swapping clusters between cars, may result in
the improper illumination of cluster indicators associated
with the above features.
