[yocto] upgrading packages in yocto

[Pandey, Kamal]

I want to upgrade some packages of poky/meta/recipes-graphics/ like weston_2.0.0.bb to weston_4.0.0.bb. Also I don't want any changes to be made in poky/meta layer. What is the best way of doing these kinds of upgradations. I think bbappend here will create problems as the SRC_URI and other variables use the PV from recipe name to fulfil some operations.
The other thing I can do is create a weston_4.0.0.bb file in my own custom layer and work but then I don't know how to disable the older(original) weston_2.0.0.bb file.
What will be the best method to upgrade packages. One thing to remind you that the SRC_URI is not a repository , it's a tarball repo. So I directly can't replace the SRC_URI in .bbappend file.
Any leads regarding this will be appreciated.
