I've heard several songs where the chorus is sung in a lower range than the verses, and in pop especially it's not impossible to find songs that do what you've done. The reason why typically it isn't done often is that the chorus is usually high-energy compared to the verse, and it's hard to convey that energy in a lower range.
Examples? Michael Jackson's "Don't Stop 'Til You Get Enough" has a higher range in its verse than chorus (but it's pretty close). "Staying Alive" by the Bee Gees is also very close, but most parts are higher in the chorus. Taylor Swift's "Bad Blood" is a current example, as well as "This is America" by Childish Gambino (this is more common in rap/hip hop, as the transitions from verses to choruses often are decreasing in energy).There are many other examples, I just don't know of any way to easily research that statistic.
Generally, it's not common in genres where the chorus is usually a climax of energy; however, some, like rap/hip hop, often have verses as the important parts of the songs.
