Of course, as stated by awk copying multiple files named "core" in a single destination directory you will end in overwriting all the files. You will get in the output dir only the LAST found core file!
Maybe you can substitute the "cp" command with a custom shell which appends an incrementing number to each core file before copying that in the out dir.

gcore
gcore(1) User Commands gcore(1)NAME
gcore - get core images of running processes
SYNOPSIS
gcore [-pgF] [-o filename] [-c content] process-id...
DESCRIPTION
The gcore utility creates a core image of each specified process. By default, the name of the core image file for the process whose process
ID is process-id will be core.process-id.
OPTIONS
The following options are supported:
-c content Produces core image files with the specified content. The content description uses the same tokens as in coreadm(1M). The
-c option does not apply to cores produced due to the -p or -g flags.
-F Force. Grabs the target process even if another process has control.
-g Produces core image files in the global core file repository with the global content as configured by coreadm(1M). The com-
mand will fail if the user does not have permissions to the global core file repository.
-o filename Substitutes filename in place of core as the first part of the name of the core image files. filename can contain the same
tokens to be expanded as the paths in coreadm(1M).
-p Produces a core image file in the process-specific location with the process-specific content for each process as config-
ured by coreadm(1M). The command will fail if the user does not have permissions to the per-process core file repository.
OPERANDS
The following operand is supported:
process-id process ID
EXIT STATUS
The following exit values are returned:
0 On success.
non-zero On failure, such as non-existent process ID.
FILES
core.process-id core images
