If that's true, I would think they could command it to use the full filter width and uplink a signal that fills only part of it. Why it would matter whether that signal was centered in the 62.5 MHz width? I guess we can't discount the fact the Spaceways are weird animals - even in non-processor mode there may be limited processing going on that would cause problems with this scenario.
Worst case, SW2 should be able to share with D14 and use only transponders 1/2 on the US, and use 1/2 & 3/4 in PR. If they don't have a better plan for it, why not? It has fuel life until sometime after 2020 so I can't see them retiring it, but who knows if it will remain at 99? I suppose they could sell it to someone who would make better use of its processing ability.
Due to the spacial diversity of the spot beams, they can continue to use all 6 transponder frequencies currently aimed via spot beams at PR. They would not interfere with any CONUS spot beams on D14. I suspect that D14 will pick up all of the CONUS spot beams on KA-hi from 99 over time and SW2 will be used for other markets. If SW2 is like D14, they can't change the center frequency by offsetting the uplink. According to what I have read, they demodulate the up link to baseband and remodulate on the new center frequency.
Without going to higher frequency transponders, there is no more capacity on SW2 for PR spot beams.
