Susan Thorpe introduced Homophonic Relationships (HR) in the February Kickshaws (07-41) in which a phonic part of a word is a related word, eg, "forestry: tree". When she asked for further examples, I doubt she had in mind this many, but she had stumbled, literally through the back door, into an area I've been going at for awhile I call Definitive Homophones (DH), where a homophone of the whole target word or phrase is a synonym or strong affinitive.
