Should I use the same series of driver for the Midrange and the woofer?

I wanna build a 3-way tower. I was thinking about using the Dayton Audio Reference 5" paper cone for the midrange and the Dayton Audio Reference 8" paper cone for the woofer crossed over around 400-600hz. Are there issues with using the same series of driver for the midrange and the woofer. I know the the 8" isnt a subwoofer, but I wanted the speakers to look the same. Thanks.
