Yes, this is the correct way. I had a script long back for this but not sure if its on my external hard disk now.You can attempt to alter the wallpaper in group policy.
I haven't tried this script using SCCM. you can check and let us know,
1. Download Bginfo.exe
2. customize the wallpaper using this file
3. create BGI file
4. run the script
reg add HKEY_CURRENT_USER\SOFTWARE\Sysinternals\BGInfo /v EulaAccepted /t REG_DWORD /d 1 /f
Bginfo.exe CustomInfo.bgi /TIMER:00 /nolicprompt
