It would appear to be somewhat taxing, just looking at the effort required to remove the old LCD.  I'd like to review the instructions for this mod, but I can't find the instruction sheet for this upgrade on the Elecraft site.

Since I use my K1 as a battery-powered portable rig 95 percent of the time, my major concern would be the increase in steady-state receiver current consumption of 10 to 20 percent for display illumination that can't be turned off without using some ersatz technique.  

Maybe it's time for a K1A, with menu controllable LCD illumination AND a display that shows the whole frequency at once and not just the last three digits.  I realize that, due to exhausted I/O capability in the current K1 MPU system, these suggested features would *not* be trivial to implement, and that they would require complete replacement of the re-designed front panel board to backfit to older K1s.  I'd be willing to pay for one of those.

Realistically, I don't expect to see any further development of the K1 product line.  I suspect that KX1 kit production costs are significantly below those of a K1 kit.
