Wouldn't it be easier to run 10.5 EmuNAND rather than this workaround. I understand that this workaround may be necessary once Nintendo figures out how to either block or detect EmuNAND on a later firmware but for now, I see no reason to not be on 10.5 EmuNAND.
It's only really useful for N3DS RxTools users at the moment, since they're stuck on 9.5 unless they switch to Rei or Cakes. Or, I guess for users who are uncomfortable about updating, regardless of their reasoning.
