Nah, LSD for all three would be ideal. That way the power is getting sent to the tires with the most resistance, i.e. traction usually. The LSD is basically the inverse of the current diffs current diffs, which are simple viscous diffs, sent power to the tires with the least resistance, i.e. diffing out.
Locking a center diff is the same as running a Savage gearbox; 50/50 power split between front and rear. Just the center diff is more compact and doesn't reduce the gear ratio as much. The higher viscosity of oil you use the closer you get to a locked diff.
LSDs are fairly complex, so I don't know how difficult it would be. The issue would not be minaturization itself I would suspect, but getting a smaller scale version that can handle the power outputs (which are NOT scale) that we are delivering these days. Also would be manufacturing costs vs resale costs. The simple diffs we use are very easy to manufacture and assemble (for RTR purposes).

but LSD for front and rear would be great... Stop the inside tyres unloading when turning
