No. As the file is a binary file gpg doesn't expect any line breaks in 
this file.

For your information, I once fixed a bunch of jpegs which where broken 
in a similar way. I could fix images with up to 6 (six) errors. Trying 
to fix a file with up to 360 possible errors is IMO hopeless. But maybe 
you have luck. It would help if you knew the original file size. But 
the best (and easiest) way to solve your problem would of course be to 
make your client resend the file in BIN format.
