I don't think that coating the MAb to the well would be
very efficient.  How about a batch process using your
MAb linked to NHS activated sepharose (or a hydrazide derivative),
but instead of using a column, use a small amount in a microfuge 
tube and allow it to mix (possibly overnight @ 4C).  Then spin 
down the beads, decant supernant, wash and spin X times, and elute.
The beads would be more efficient than wells, providing
greater yields, and the batch process wouldn't use up as
much antibody as required to prepare a column.
