Thanks for the quick reply. I can't create a new patch right now, but I'll edit this later when I test your suggestion. Interestingly, I uncommented all values for all devices in 3.17.3 and the output file was created without any problems. So it looked like:

find_base_address = `ReadingFooter {\n\tmin-height: 70px;`
#
# Replacement footer height values: Touch/Mini
replace_string = 0011, `min-height: 70px;`, `min-height: 32px;`
replace_string = 0024, `max-height: 70px;`, `max-height: 32px;`
# Replacement footer height values: Glo/Aura
replace_string = 0085, `min-height: 82px;`, `min-height: 40px;`
replace_string = 0098, `max-height: 82px;`, `max-height: 40px;`
# Replacement footer height values: AuraHD/H2O/GloHD
replace_string = 00DA, `min-height: 120px;`, `min-height: 036px;`
replace_string = 00EE, `max-height: 120px;`, `max-height: 036px;`

EDIT: Thanks, Geoff. I produced the output file without error and the footer height now conforms to my tastes. A few issues other I've noticed which might be addressed by existing patches:

-in epubs text weight in advanced fonts doesn't have effect on the Publisher Default which I favor
-epub line justification also seems to have no effects across several epubs with and w/o Publisher Default font
