Thanks much Riki!

For anyone following in my footsteps, the solution to the lack of
extended fonts for a layout derived from extbook is to add the
following line as the first non-comment line of your layout file:

Input extbook.layout

Then close LyX, run texhash again, then run again, then
open the LyX file set to your home grown layout, and you'll now see all
the font sizes in Default Family of Document Settings/fonts.
