I looked at glasses.el, and it *already has* that feature!  Set
`glasses-separator' to an empty string and `glasses-face' to e.g. 'bold
(the symbol - name of te face).  Note: use customize-option.

If you really want to highlight every other subword, not just the
initial letters, check out this proof-of-concept implementation:
https://gitlab.com/-/snippets/3614958 .  I plan to blog about it on Nov
11.
