perl -p only reads one line at a time, so you're never going to match "\n\n"
that way.

If the file isn't too huge (i.e. can fit in memory), you can do this:

perl -e 'undef $/;  $_ = <>; s/  2\n\n\n/  2\n\n\n\n/g; print' FILENAME
>NEWFILE

Otherwise, you'll have to actually write a program of 5-20 lines.
