they could make ultimate out of anything they felt was worth the dev time
I suspect an alexander ultimate that involves fighting a ton of goblin war machines and the voltron parts and brute justice while a giant alexander is in the background shooting lasers across the arena would be in the works
warring triad would be pretty amazing but also that would be an ideal phase one of kefka ultimate imo
with as much time as nidhogg got as the main villain a steps of faith ultimate where you actually fight off a huge dragon onslaught ending with a duel against nidhogg makes sense
