Name and version of the dkms modules to remove is not easy to guess in a global hook. Also note that a dkms module can build several kernel modules. That's also why registering (dkms add) of the modules is done by install scriplet. Only the build/install of registered modules are done by the hook in order to schedule them properly.

With these hooks [1] designed for kernel transaction, we will have complete support of oot modules in pacman.

I didn't tried them but I don't get how this can works when you install/update a dkms module.  Your dkms-install hook is triggered by files installation in /usr/lib/modules, but dkms packages didn't do that at all. They write these files in /usr/src/$foo and register the dkms module with dkms add. Files are copied in /usr/lib/modules when you run "dkms install" (so not under the watch of alpm), so it make no sense to call dkms install again when file are here.
