The easy part is the stepper motor driving and stuff. The hard part is printing a whole new gauge face that makes sense and looks OEM. If it is something you want to do (and it is something I kind of want to do, but haven't gotten to yet) you might want to talk to someone who makes gauge faces. I know that the cluster can be taken apart and put back together without screwing things up. (several companies do make these: http://www.86worx.com/subaru-brz/int...uge-faces.html).
If it were me I'd go through these guys: http://www.metal-monkey.co.uk/acatal...nd_Gauges.html I had them make me cool HVAC faces for my miata. They do very precise work and have reasonable prices. I know a lot of their stuff looks kind of garish and ricey, but they can make subdued stock looking stuff. One could probably get into a business of cluster customization (lighting, needles, dials, startup sequences, digital displays embeded, other analog gauges hacked in, etc.)
So, the big question is, what would you put in that huge space on the cluster?

Sort of like a Android TorquePro but with a different display.
Now to find a "surplus gauge cluster" to begin experimenting with.

i am of the same mindset-- put at least one, or multiple lcd's in that location--very likely multiples, as i want to retain most of the warning lights in that area... i've got little use for the oem stepper motor, though i'm aware there are plenty of documented methods for driving it if i really wanted to use it for something...
and btw, surplus/wrecked gauge clusters are all over ebay-- fair market is roughly $100-150 or so.. i got one a while back to play with backlighting techniques.. again, haven't done anything with it(it's easier to play around on the computer then do actual work on all my car projects)..
