I am sorry to disagree, but the MH2 will work fine for both the K2 and
K3. They are interchangable. After the repair and configuration of
over 1000 K2s, I am quite familiar with the K2 microphone configuration
for various microphones.
Yes, the K2 mic config header must be jumpered properly and have a bias
resistor soldered between pins 1 and 6 on the rear of the mic jack, but
once set up it will work. The original poster has his K2 set up to use
that microphone already.
Moving it to the K3 is simply a matter of setting the MIC SEL menu to FP
L Bias.
If the MH2 mic fails, the MH4 is a direct replacement.

Download the MH2 instructions from Elecraft site and you will see that the
mic has different jumper settings for the K3. I’m not sure if an MH2
configured for K2 will work unchanged with K3. The K2 config in the mic
has a resistor that is not there for K3. At least that is the way I read
it.
Bottom line: mic should work fine with either rig but not interchangeable.
