nah, she only came up with a solution to use FGemunand was kate's job and she quite their team..
EmuNAND is and was SciresM's baby
As far as we know a sysNand solution like A9LH or Sighax won't come for the switch in a long time (or ever).
8Bit is right you know...A9LH/B9S or Sighax are bootrom exploits, which we have on the Switch.
I guess you meant to write 3DS instead of Switch here because there is no such thing as B9S or SigHax on the Switch.
RCM and SigHax type of exploits are fundamently different. Only common thing here is that they are low level entry points.
