To be honest, I think the biggest problem with the switch pack is the location directly in front of the cup-holders. I suspect most replacements from a breaker will have the same accumulation of sticky gunk in them as a result of 10+ years of beverage spillage.
That said, if they're cheap enough there's no harm in swapping them over. The rocker switches themselves are pretty robust units though, so could well be that a good clean is all they need.
