Nah, Stomachache hurts so much because it happened with Io out of all people. No other girl can have an event similar to Stomachache.
Io has that innocent-like aura around her, when she's alone with Akira. She was one of the girls that genuinely like and care about him and NOT his dick. Io's past is tragic and her recent confrontation with Nodoka also participated in this pain that Stomachache caused to most of the players.
But even if Sel decided to create a Stomachache event for Yumi, it wouldn't be very impactful. Yumi kinda always expects Akira to blackout around her, and Yumi has experienced some level of rape-like stuff from him. So, making Yumi experience this again would not be interesting from a storytelling perspective, because it has always been her for some reason. Also, for example, even if Akira decides to fuck Yumi just to show his love when she is extremely vulnerable (such as during 0.48 when they were at the love hotel), I believe that Yumi will either run away, breaking off their relationship again (And it will not happen, I believe, since Sel's writer ego won't let him repeat the same thing over and over and over), or accept it wholeheartedly.
Though I would like Stomachache-like event with any girl in LiL. But again, it wouldn't be as impactful as Io's Stomachache.
