You can do that with PTXdist. Enable PROJECT_USE_DEVPKGS (this is right
next to PROJECT_CREATE_DEVPKGS) and set the path to the directory
containing the *-dev.tar.gz.
For any package with a matching *-dev.tar.gz PTXdist will skip all stages
including "install" and extract the archive instead. The rest
(copying the files to sysroot, targetinstall, etc.) happens as usual.

Note: just manually extracting the *-dev.tar.gz to create a sysroot will
not work. PTXdist does some magic to make sure the paths in any "*.la" etc.
match the new sysroot.
