Can the LT3045 be used to regulate both a positive and negative voltage rail?

I would like to use multiple LT3045s to produce a quiet, well regulated, bipolar power supply.  The input to the two linear regulators will be from two isolated DC/DC converters.  My intent would be to treat each DC/DC converter-LT3045 subsystem as an electrically independent subsystem and then to tie together, at the subsystem outputs, the "ground" of the positive voltage subsystem to the +voltage rail of the negative voltage subsystem to form the common return path for the bipolar power supply.  I am not sufficiently experienced to know if there are issues in accomplishing this that I do not understand.  I am exploring this as a option because I have not been able to identify a negative linear voltage regulator that has similar characteristics to the LT3045.
