Image rejection is not the problem. 

The big problem with putting a K1 or K2 on 60 meters is IF 
feedthrough/rejection. On other bands the selectivity of the signal-frequency 
tuned circuits can be counted on to knock down the IF feedthrough somewhat, 
but with the IF on 4.915 and the signal on, say, 5.2, most of the job has to 
be done by the inherent rejection of the balanced mixers. Which may or may 
not be adequate for the job.

You can be sure that if it can be done, the folks in Aptos will figure out 
how to do it.
