I tried the subdepth package; with pdfLaTeX the result fine and seems 
like exactly what I needed, so thanks again.

For LuaLaTeX, otoh, it does not work, for both TL2015 and TL2016 
settings. ”not work“ means there is no error but also no visible change 
in the output with/without the package.
Does LuaTeX use other fontdimens? What can I do to make the code work 
with LuaTeX?
