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.
