This is a very interesting discussion! I found some similar lines in Savitri. Similar in the sense that they have 10 syllables each, they all begin with "He has" or "She has" which can be scanned as pyrrhics, and the second foot can be scanned as a trochee: He has| reached' the| world's' end| and stares'| beyond';| He has| re'found| the skies'| from which'| he fell'| She has| ac'cep|ted as| her Nat'|ure's need'| Do these scansions look OK? Also, I am a bit confused about the actual difference between the two scansions: |He has made'|a thick'| and narr'|owing hedge'| and |He has|made' a|thick' and| narr'ow|ing hedge'| I was recently reading in an article that a foot like the iamb or anapaest that ends with a strong syllable takes longer duration than a dactyl or trochee. This is apparently because in an iamb or anapaest more time is spent on the strong syllable than in a trochee or dactyl. This is in an online article discussing the difference in durations between iambs and trochees. For instance the iamb |I am'| takes longer duration to utter than the trochee |I' am|. If this is true then perhaps, in the second reading, there is no need for a short pause after the "has" in the first foot. Rather we need only reduce the intervals between "made" and "a", likewise between "thick" and "and", as also "narr'" and "ow" to produce the effect of three trochees... These are just some thoughts I wanted to share. Please correct me if this is not standard in english prosody.
