This is why I use NASA in ReiNAND EMUNAND 10.3 whcih let you install FBI.cia onto EMUNAND.so let's try and make this clear...
I tried using hblauncher_loader (which would have the same effect even if I used browserhax or Cubic Ninja) in ReiNand emunand with FBI.3dsx and was not able to install anything.
I was able to use FBI.3dsx to install things to rxtools pasta mode (sysnand). so I could then install FBI or BigBlueMenu or whatever.
I highly suggest installing in sysnand before cloning it to emunand.
