Thanks to new
Export/Import Notes action, I was able to bulk edit the html and fit nicely the notes generated in the book details pane.
It was cool to find that Notepad++ can process 1600+ files all at once, though I'm sure there must be some text replacement tool more fitting to this task.
These were the replacements I made:
--------------------------------
font-size: xx-large
font-size: large
----------------------------
<img style=
<img width="140" style=
-----------------------------
font-size: 14px
font-size: 12px
------------------------------
<h1
<h4
-------------------------
h1>
h4>
