It depends on your perspective.

Personally, I feel that if a new spell is being added, especially one as iconic as Ultima, it should bring something new to the gameplay of BLM as opposed to being just a potency upgrade to an existing skill. Like, I'm never excited about getting a new level of Stone on WHM because despite its new animation, it's still just Stone plus a bit of potency.

I don't want to get that feeling from Ultima where it's literally just Foul, just with more potency.

Creating a new resource is one option. Just like how Polyglot was created for Foul, have something new to build up for an Ultima spell. So it changes your gameplay by having you work around this new resource and how the cast of Ultima then fits into your rotation (Where replacing Foul just means that whenever you'd Foul now, you'd just cast Ultima)

An example would be something like making Astral Hearts and Penumbral Hearts be a thing generated from a specific Fire/Lightning spell respectively. With Ultima then costing 3 Umbral Hearts, 3 Astral Hearts and 3 Penumbral Hearts (Also then meaning you would need to regain those Umbral Hearts to do your next Astral Fire phase at the normal 313 ratio or would instead just skip the refreshing of them and do a weaker 3-4 Fire IV's and then swapping).

Another example could be something that stacks up whenever you generate a new Astral/Umbral stack (So 3 per swap between AF/UI) and once you get enough stacks you can cast Ultima.

Maybe an "Enhanced Polyglot" that requires you to spend X time in both Astral Fire and Umbral Ice phases with Enochian active in order to activate, potentially making it a DPS gain to spend more than 2 GCD's in UI.

There's plenty of possibilities that can make a new massively powerful spell an interesting addition to BLM's kit without just pasting it on top of Foul.
