What do you think Nintendo could do to improve Kirby?

I've always been cognizant of Kirby not being up there in the higher-tiered fighters, which is a shame because I always thought he was so fun to play as/against(especially eight of them at a time). Taking that into consideration, what do you guys think Nintendo could do to make him more viable, or at least do to improve upon him so I don't always "feelsbad" when I see him in lower tiers when people rank the fighters?
