Wack music theory question of the week.

So I'm working on this handbell quartet arrangement of "Fum, Fum, Fum," and the song is largely in cut time (i.e. 2/2) with a 3/2 measure thrown in at the end of every verse (because that's the way the song goes). Anyway, there's a point in the song where I want to throw in a 3/4 measure just to jazz things up, but since I still want the half note to get the beat, should I instead call it a 1.5/2 measure? Assuming my music program will let me do that? Which of course it won't?
