Would
java.util.SequencedMap.of(...)
java.util.SequencedMap.copyOf(SequencedMap map)
java.util.SequencedSet.of(...)
java.util.SequencedSet.copyOf(SequencedSet set)
solve your problem?

I would love to see them included in JEP 431.
Should be fairly simply to implement just have a side
array that maintains the elements in order.
