Merging Julia Packages folder

in .julia folder there is another folder named packages.
Consider two computer systems totally Identical. These PCs have the same version of Julia, Totally identical in every aspect. On system A I have a set of packages, for example,Pkg1, Pkg2 and Pkg3 and their dependencies. On system B I have also a set of packages, for example,Pkg1 (same as system A) Pkg4 and Pkg5 and their dependencies. Now the question is:
Is there a safe way to merge the system A and system B packages folder?
And if this is safe what should I change after that?

I think you will have the manually “merge” the Manifest.toml and Project.toml besides copying all the folders. IMHO, it’s not worth it.
