Parallel outputs of AD5737 for additional current drive?

I have a customer looking for a low cost, precision current source.  He wants a SPI interface and current up to 30mA.  Output voltage could range up to 16V.  His application does not require very high accuracy (1-2% is probably fine).  The AD5737 is a close fit using the 0-24 mA output range.  Can I parallel 2 of the outputs to get greater current drive?  If so, what is the easiest, safe way to do this?

 

Any other suggestions.  He has already considered CN0151.
