Louis XIII's Mysterious Letter (1635)

There is a letter from Louis XIII, dated 6 April 1635, which is written in the normal alphabet but is full of nonsensical words except for a few French words. (I learned of this from David Chelli and Cipherbrain.) I added this in a section in "French Ciphers during the Reign of Louis XIII".
Here is my provisional transcription:
Mon Cousin, bac racle suroaert brancher
guignanocher rip goelle harpe volduc
hagardement son bac bobe her rabo
en vol baratre her Spir, siron pincer
her lily ser, cest basco rideray son sol

Some ideas are proposed in comments to Cipherbrain, but no conclusion is reached.
By the way, Klaus Schmeh announced Cipherbrain will be closed at the end of the year. Cipherbrain manages a very lively community where people from all over the world gather and discuss various ciphers or other related mysteries. I hope some other platform will be found to host his blog.
