There's no built-in way to do that, but you achieve it with a few quick additions to the templates.
Find something like this in the templates (it should occur twice, IIRC):
<blockquote>
<var $comment>
Replace it with this:
<blockquote<if $email=~/^aa$/i> class="aa"</if>>
<var $comment>
Then add this to either the global stylesheet in the header template, or to each individual stylesheet:
.aa { font-family: 'MS PGothic', MS Pゴシック, IPAMonaPGothic, Mona; }
Finally, to post with SJIS art, just enter "aa" in the email field. Note that I haven't tested this.
