It is a non-trivial undertaking for any established project with multiple copyright holders. The license header is generally not something you are permitted to change generally unless you are the copyright holder, or have the copy holders' agreement. Despite this, we can see the kernel did such a switch, replacing license headers with SPDX tags. My understanding though, is that there was work done behind scenes with legal input before they actually merged the patches, as a means to justify this change. On any newly written project I'd certainly use SPDX, but IMHO for existing projects it isn't viable unless we see clear legal advice explaining a process to follow that makes it acceptable to replace license text with SPDX.
