Would be really cool if this did damage to enemies if you shoot them and then start a battle. Kinda like how in the mario rpgs if you jump on an enemy you'll deal damage as soon as the battle starts.
Believe me, the idea is VERY tempting. But I don't want Fran to be overused in that regard, if she can melt obstacles and help gain the advantage over an enemy, she'd be overpowered.
