Hello Tony, don't forget to pop over to the intro section and say hello on there.
To answer your question, I would expect that you are going to have to get creative in the garage to make some spacers. I can't understand why Suzuki has chosen to mount the panniers so high up, but that is what they have done. I agree about the having too wide a top box being a PITA as that is the situation I'm in with my bike...! Take care when making your spacers though, as putting extra weight too high up could upset the balance of the bike and to open the lids on the panniers you may have to mount the box quite a long way up to clear the lids.
