Your best bet would be to download the PKGBUILD file and rename the
package name. You'll probably need to make a few other changes as well
as often the package name is used to download the package etc.

Update the provides,conflicts as needed

Now you'll have a package that can coexists with all the others and
pacman won't even ask to upgrade it.
