If you pick up another display on eBay and find a source for the right length of connecting cables with proprietary plugs yes, it can be done. I did it several years ago. Dome started failing about a year later. Installation was torn out and replaced with a new dome and two new Raymarine MFDs. (Which I hate, but that's a different story.)
edit: Whoops, looks like my reading comprehension slipped. If you're thinking of connecting to the R41X no, it will not work. Different generation. The R41X had primitive networking connections to connect to a compatible Loran-C for position data, but that's it.
As a rule of thumb: if the manual mentions "NMEA 0182" and the unit is working, leave it alone. If not, get a shovel. Do not futz with it unless you're a hobbyist who likes the electronic equivalent of BDSM.
