Need help making sure my ST, STng, NMEA setup will actually work...

Question Need help making sure my ST, STng, NMEA setup will actually work...
Our boat has an existing Seatalk1 network on boat that connects the Master E80 display, S3 Course Computer, ST6001 AP Head, ST60 Wind + a Repeater, and an ST60 Tridata and a repeater. We also have a second E80 at the helm which is networked over SeatalkHS.

The Master E80 is connected to an AIS transceiver via NMEA at 38,400 of course. The AIS is the only source for GPS position data currently.

I am trying to solve two problems.. 1.) I want a redundant GPS source, and 2.) I need to feed NMEA GPS position data to my new SSB and EPIRB as well.

I purchased a new RayStar 130, plus the SeatalkNG to Seatalk converter, as well as the newer SeatalkNG to NMEA0183 kit. After reading all the manuals, both print and online, I believe I have figured out how to set this up but I have a few questions, and the information across all of the manuals doesn't really provide all the caveats involved. So if you could take a look at my diagram and let me know if this will work, that would be great! If there are changes that need to be made to make it work, that would be helpful.

My current plan is to connect the STng->ST1 converter directly off of one of the ST60 displays, and then connect a SeatalkNG backbone from that to the STng->0183 converter. Assuming this will work, I'm not clear on whether I need to supply power to the STng bus or not. Currently the S3 course computer powers the Seatalk1 bus.
