I just talked to Klaus last night, by chance. He said my 6yo Kismet in Stratos don't have any available upgrades, so I would think... no.
BUT, it seems these are highly variable between customers and Klaus keeps detailed notes. As with a lot of answers here, call him and ask. He may chime in here, but I think when he gets busy he doesn't participate as much. And it seems he got a lot of interest at CAF.
