FWIW,
I used FontForge on Linux and was able to take the LiberationMono.ttf font from its github release site, and eventually found a way to edit the OS2 tables Win Ascent and Win Descent values and generated a MyLibMono font with increased line spacing. It took quite a bit of trial and error but it was doable. To install it I just copied it to ~/.fonts folder.
Then I launched Sigil and opened Preferences and used Appearance CodeView to select the MyLibMono font and it all worked.
Even with FontForge the process involved a lot of trial and error. And according to their docs, the same changes may not work on other platforms.
So not easy but doable.
