anything is possible, its a matter or creativity, time and $.
i took a look at the grady website and the helm (dash) of the current 208, if you're is similar, then IMO it's definitely doable, just a matter of how nice you want it to look and $.
most expensive option is custom fibreglass work to cover the upper gauge area and console area and make it one larger smooth "canvas" in which to flush mount the display unit and the gauges and anything else. I'd make a hatch on top of the console as many other members have to keep some storage and access for the flush mounted stuff.
another option which i did on my 2002 282 helm is custom fab a new face from "seafoam" color starboard to flush mount stuff.
you may need to "laminate" some material to smooth the transition between the gauge area and the console face and cut material in between these 2 area to fit the large display.
Mine is not super slick as a custom fibreglass job, but it works very well and looks pretty good.
