Yep. That's the intended route, so you're on track there.

You don't have to check. See the method makeTemplate() in the Feature
interface. Call this on any Feature (which is immutable) and you will
get back a mutable Template corresponding for the Feature
implementation which it came from. You can change any of its fields if
you need to and then call createFeature(Feature.Template template) as
you describe above. This will add a new Feature to your FeatureHolder
(your OrderedSequence in this case).
Sounds like you're almost there. Let us know if you need anything
more.
