There is no need to modify jquery.sceditor.min.js, you can edit GenericControls.template.php, changing for example:
rtl: ', empty($context['right_to_left']) ? 'false' : 'true', ',
colors: "black,red,yellow,pink,green,orange,purple,blue,beige,brown,teal,navy,maroon,limegreen,white",
to:
rtl: ', empty($context['right_to_left']) ? 'false' : 'true', ',
fonts: "Moon Runes,Ringbearer,Whatever font you want",
colors: "black,red,yellow,pink,green,orange,purple,blue,beige,brown,teal,navy,maroon,limegreen,white",
That will directly add the fonts you want into the dropdown and use it into the posts.
I'm telling you this, because the "min" files are always replaced in case of updates, so any Elk patch that will tweak the editor (like the upcoming 1.0.10) will blow your edits. 
Is it possible to access a topic using this font?
