I'm not assuming anything, I'm basing this off of the fact that:
 * 1) Lucy has never seen Franmalth's attacks like Natsu and therefore couldn't possibly know anything about his absorbing abilities, and
 * 2) Both Taurus and Aries barely landed a blow (they only distracted) and Franmalth got them.

Sure, she could summon another Spirit. But, would Lucy, who we know values her Spirits lives very well, really want to put another in danger or force them to fight their friends? Like she would summon Loke if Fran can make Aries face appear >__>
