A possible 43S case?

I've got only a 300S. I opened it today, drilled up the heat stakes, and found (unexpectedly) individual keys; these keys aren't hinged in any way but sit on a common rubber mat. The rubber mat looks identical under the cursor block like under the other keys, just the diameters of the key contact circles differ. The (slightly rounded) rectangular key holes in the front plate are 11 mm wide and 7,9 mm long for the big keys and 9,2 mm wide and 6,2 mm long for the small keys.

If anybody has disassembled a 300S+ to that stage: it would be interesting to know if the keys of the 300S and 300S+ are interchangeable. If true, the keys of a 300S in a front plate of a 300S+ may combine the best of these two worlds.

To make my suggestion crystal clear: I don't recommend copying the 300S or 300S+ in any way for the 43S - I just think we may butcher these low cost calcs to get some parts we can re-use or repurpose as long as we can count the really existing 43Ss easily using zero, one, or two hands. Producing our own plastic parts may become economical significantly later.
