ADR5045 Voltage bias for a voltage divider

Question

Hi 
 I would like to measure the voltage with a voltage divider. 
 I would like to bias (offset, subtract) 5V with the ADR5045BKSZ-REEL7 from a 6-16V Voltage Source. 
 My current scheme is this: 
 
 I have calcuted that the Total current should be betwwen 75uA (6V Input) and 820uA (16v) Input. Max Voltage Output is about 3.5V, Minimum about 0.3V. ( Spannungsteiler, belastet ) 
 I have seen on another post that somebody made a similar circuit with a TL431 variable shunt regulator: 
 
 Do you agree that my solution should working? 
 Thank's very much for every input 
 Andy
