How hard would it be to replace an analog gauge cluster

Depends on the car.

Why would you replace a nice looking cluster with ricey trash?

It would be very easy if some of them came out of the factory with a digital display. If not, you'll have to rely on aftermarket shit or make something on your own.

Unless it was something intended by the manufacturer to go into the vehicle, be very careful. Accurate readings are more important than anything.
