Because some program only accepts V(B) data? Because of input dataset 
concatenation or output DISP=MOD issues? As a test to see if some program 
handles VB correctly?

I can think of lots of good reasons.

Subject: Re: IEBGENER REblock FB--VB

If, with EXEC PGM=IEBGENER, your SORT product is used, you will see ICE or WER 
message prefixes (preficies?).

You want to copy an FB to a VB, with no further changes? Why? The point of 
variable-length records is that they are... variable in length? All yours are 
going to have the same length, four bytes longer than the original. Unless they 
had an inefficient blocking-factor originally, all you've really done is 
increase the overhead in processing logical records.

Why do you want a VB data set with all the records the same length?
