Will playing in a slowpitch softball league have any effects on my baseball swing?

I was just wondering this because my friend really wants me to play in his softball slow pitch league because i play baseball. I have been a pitcher, but finally just started to focus on my swing for baseball wise to improve that so i can be a decent hitter and pitcher on my DIII college team. I am afraid it will hinder my swing and get me into bad habits since it is different. Let me know please!
