No, the hackmii installer doesn't work as the current exploit was patched, and it deletes the HBC every time the system is started. Currently, there is no way to do anything that writes to the FS using homebrew. You can still run any homebrew that doesn't use the NAND and doesn't require a cIOS using StackSmash, but that doesn't let you do much. Until we see a new Hackmii Installer and hopefully a new TBR people on 4.3 are stuck. New Hackmii installer should hapen in the next week or so, and a new TBR will hopefully happen in the near future as well. Just wait for now.
