Because it is public domain, we can be freer.

Keep the structural melody recognizable.

On a repeat:

• preserve phrase beginnings
• displace one connecting note by octave
• add one wider approach into phrase 3 climax
• use a fourth-based fill between phrases
• return to the plain melody at the ending

The result sounds like a true paraphrase rather than reharmonization alone.
