 http://www.zlib.net/zlib_faq.html#faq11 talks about command line
program whose source code may be reused for the purpose?

This relates to the most morphologically complex languages of
course, e.g. one polysynthetic I am currently working on. Typical tests
at converting hunspell dictionaries to automata I've done have created
automata of sizes ranging from few kilobytes to 10 megabytes, and same
for most floss fst morphologies that can be found by searching the net.
Also it's most likely entirely possible to optimize the automata using
some automatic (tbd) or manual (flag diacritics, etc.) methods, but
these of course require further programming work as mentioned.
