Using the ADG715 as a step-attenuator

Absent a DAC, I need to drive an ADA4700-1 configured to produce from 0 to -38V.  The design requires from 0 to 2.5v for this span.  For a set of 8 fixed voltages, is it practical to use the ADG715 to switch a series of voltage dividers to drive my voltage source?  (I call it a step attenuator)

Roughly, this:
