look at 240.21(b),430.28
the answer is NO you can not.
the feeder/tap MUST terminate at an OCPD...the feed throught lugs of a panelboard ARE not an OCPD.
another problem is the ocpd for the panel wont cover the protection requirements you need.
that said..if the panel will handle the additional load i would just install a disconnect/ocpd next to that panel and feed from that.
hope that helps..
