You can, but if you do that multiple times, you'll end up with multiple 
keys with the same kvno.  Since Heimdal records for each record the version 
of the master key that was used to encrypt it (if any), it can handle 
multiple keys and do a gradual transition.  But that won't work if you keep 
reusing the same version.

Also, that's rather convoluted compared to

ktutil add -r -p M/K
