Main Class Change/ Dual Class Event or Service?

Will there ever be an event or service where we can change our main class to something else, but keep our dual and subclasses the same? Or maybe make our dual class the main class? My character is a 91 Summoner and I honestly am sick of him. I play almost exclusively on my dual class Archer. This character has several essential items on him that can't be traded and are too expensive to get again, like three level 4 jewels and +9 shining shirt. Otherwise I would simply start a new character. It would be nice to have an event or service where we could change the main class.
