Double first base question

[Big Slick]

This play is mostly for ASA (since it involves the DFB and language in Rule supplement #1):

No out, no runners on. B1 hit a ground ball to F6, and arrives at 1B before the (errant) throw (note: the errant throw is in the dirt, so this will constitute a "play at first"). B1 touches only the white portion of the base. The ball subsequently goes out of play, to which the umpire declares "dead ball" and places B1 on 2B. B1, who legally over ran 1B, proceeds directly to second base.

Question: if the defense appeals that the batter missed first base (by not being in compliance with the rules pertaining to the DFB) should we grant this appeal and declare the batter out?

I would really like to say that we can (after all, the runner has not complied with their base running obligations). However, in Rule Supplement #1 (Appeals), section about missing a base, language pertaining to DFB states "the appeal must be made before the runner returns to the base and the ball is live."

What do you think?
