While fixing up one of my AEK II last night I did a little experiment, I took the switch top, spring, tactile leaf and slider from a loose SKCM salmon switch and swapped it over onto the AEK, replacing those parts in SKCM cream damped switches. I then did a 1/2 test against another AEK with normal salmon switches. They felt identical.
I'm considering doing this to a full board, the switch plates appear identical, the bottom housings are a tiny bit different, but I don't think it contributes to the feel at all, the two little nibs that the slider strike are wider in creams.
I've previously done a full switch swap from bamboo white to get an ISO AEKII with salmons which was a huge hassle but the resulting board is my best, so I have a perfect board to compare with. I bought a couple of hundred loose salmons so will do the rest of the board and see how a full swap compares to a "top swap".
I dunno if it'd work with bamboo switches, swapping slitless tops with slit tops.
Edit: Tried it with bamboo damped white, works exactly as well, the switch bottoms seem functionally the same, but the little nibs are even bigger still than pine damped creams.
