I've actually been working on a socketed ram mod but as you can imagine routing a FBGA200 pin footprint is rather hard, specially socketing it while considering characteristics such as EMI, trace length, frequency matching and etc, not an easy task and I've been at it months; if I do then it'll be fun to be able to change it on the go due to how you can modify the rear shell to have a laptop style rear door, but I'm yet to buy a proper 3D Laser scanner for this type of replication(I cba to measure and do CAD screw that.), L4T Emulation and etc will most definitely benefit, remember any modification that increases resources will always help, it's just about the hands it is in.
