What error message did WAD Manager 1.3 show the last time you tried this? Is there a chance you tried downgrading the IOS used by the System Menu (which in my case is IOS50)? I take your word that it is not possible on your Wii, but rest assured it worked perfectly fine on mine. In fact, I uninstalled my existing cIOS rev 07 just for this purpose, rebooted the Wii, started WAD Manager 1.3 and made sure the message "[+] Custom IOS detected and loaded!" did not show on the WM welcome screen any more (which to me means WM is hanging off Homebrew's default IOS36). I went on installing IOS36-64-v1042.wad over my factory IOS36 v3090 without issue.
I'll stop trolling now, but just wanted to mention that your experience might not be the same for everybody else.
