It's my understanding that as of z/OS 1.5 BPAM using BLDL (but ironically
not DESERV) handles mixed concatenations of Classic and HFS directories
transparently (note revision bars):

#     1.1.2.2 "z/OS V1R5.0 DFSMS: Using Data Sets"
     _____________________________________________________________________      
   
                                                                                
                
  1.1.2.2 Basic Partitioned Access Method                                       
                
                                                                                
                
   | Basic partitioned access method (BPAM) arranges records as members of a    
                
   | partitioned data set (PDS) or a partitioned data set extended (PDSE) on    
                
   | DASD. You can use BPAM to view a UNIX directory and its files as if it     
                
   | were a PDS.
