In response to your Option 1 & 2 for getting rid of drone, are you sure adding those side branch resonators will remove the drone? And if so are you sure they won't change the exhaust note to something you don't like? Cutting into the exhaust seems a bit drastic but make sure you're prepared to deal with it if it doesn't turn out the way you want.
I would be more inclined to just sell it and get one with no drone like the HKS (or so I hear) or whatever the cheaper alternative is.
