Hi, Chan Tran;
As I have changed "guts" between halfnuts and fullnuts, I can tell you it is possible. You'll have to cut ALL plastic rivets in both units and change the mainboard (it's a keyboard/mainboard/display driver in one piece). Then you'll have to fix both units back, using one of the techniques already mentioned here.
If you want to keep the blanknut "layer", I see no other solution. BUT... if you are not willing to keep it, maybe you can trade your CX blank nut for a conventional CX halfnut and have some money back, if applicable. Rememember that many CX in a box were found last year and sold as new units. If you believe it's a good deal, a "fresh new" CX might be a good solution as well, and you'd keep both CV and CX (plus the blank nut) untouched.
If you still need to change their guts, I have some images with the location of the rivets. To be honest, I'd not disassemble a working 41... It's a pain to dismantle it and join the pieces back together. I've done it a few times, and the units actually needed service. Otherwise, I'd not do that. My opinion, of course. (and I apologize posting it here because I was not asked to...)
