And, the 144 and 432 MHz TX section uses a different PA section.  So if you loose full output on the HF portion of the rig, the radio could still function as a fine all mode 144MHz and 432 MHz radio.

Not necessarily!  An all-mode rig like that (no finals) would make an acceptable IF for a microwave transverter stack.
