A bit late reply but I think you can do the following:

- Treat the different exposures as functions (split into R + G + B)
- Combine these into new functions using "select": use value
   from longer exposure by default, pull values from shorter exposure
   where longer exposure is above some threshold (e.g. 0.9). When using
   value of shorter exposure divide by appropriate factor (depending
   on difference in stops)
- Render combined function pigment with HDR output
