Nope. It's encrypted and signed such that without Nintendo's private keys for that it can't be done to my knowledge.
I was kinda wondering, though, if the system menu would run unencrypted you were to were to save it as a separate title (assuming IOS only tries to decrypt something if it sees the system menu's title ID) or if you run it with a different IOS (assuming IOS80 always wants an encrypted title, knowing it's only supposed to run the system menu) either way, though, you would probably have to deal with the issue that the system menu and 1-512 used to run an unencrypted title would want to use the same memory addresses.
as far as autobooting the unencrypted version, you also might be able to replace the original system menu with a copy of 1-512 with an extra section added to the DOL to also write the new title ID into the right address so it will see it once it's done decrypting and load that title instead.
That's what's occurred to me thus far, at least.
If by hacking the wii u you're talking about getting all 3 cores to run together in a usable way, yes, slow progress is being made. At this point all 3 cores make it to the Linux kernel but it's still only using one of the cores to actually run stuff.
