I don't think that any ham radios also operate on those frequencies. it is possible, and of course if you modified the radio to allow you to transmit on those frequencies, then yeah it would work. But I think most if not all legal ham radios will only allow you to transmit on the ham bands.
I think your best bet would be to have both a CB and a ham radio if you need both, but of course then you'll have to rock a dual antenna setup or have both radios using the same antenna, both of which would cause some issues (though still you best option)
many ham radios can also receive other frequencies, you just won't be able to transmit without illegal modifications.
