is there anyway to get a view with different types of components, but that they match a certain compile time predicate?

No, there isn't.

Is there anyway I can get all the entities that have components A or B?

The simplest solution is to redesign your component and turn the template parameter into a member, so as to have a single type to filter later on.
Another option is that of using listeners for IsEnergy<T> pools that fill a storage<void> pool somewhere else with the entities of interest. Then you can use the latter to construct your view.
You can also refine the last approach with a mixin to make it transparent/automatic. All mixins receive the registry after all and they know when an element is emplaced or erased, so 🤷‍♂️ the sigh mixin is an example to take inspiration from eventually.

I assume this was answered. Feel free to continue the discussion here if this isn't the case. Thanks.
