Don’t think so. I remember the original bassist being ‘musical differenced’ out of the band around the time they were getting big/going shit but don’t think he was any less attractive than his replacement so he must have just objected to the ‘going shit’ tactic.
The keyboard player who looked a good ten years older than the rest of them seems to have left more recently but far too late for it to have been any sort of marketing move, think he just left. Not sure about anyone else.
Worth noting that the despite the cynical move from half decent indie band to bland radio schmaltz, Lightbody does seem like a genuinely lovely fella and makes an effort to promote new NI bands and stuff.
Also donated a load of his old CDs to Good Vibrations when it was still open (I bought a Clinic and an Avalanches album off him)
