Unfortunately I am not able to find any movement on that functionality request. I only found a solution posted against Robotics in the post Convert a word document to pdf format. I also found a solution using apache POI to convert ms word file to pdf suggested here - is that an option for you?
The enhancement request that you logged against Pega is still open: FDBK-25889 (Amyuni Word to PDF converter replacement)
I will see if I can get an SME to review your options or whether there are any plans in the pipeline.
