Replacing s2 with ev-200

[riptyler]

I have 2 e80 displays, DSM300 and HD Radome (connected to HS switch). I have a Remote, 2 Depth units (40 maybe?) and one ST6000 AP heaad. GPS was replaced by prior owner and I have no idea where it is interfaced (suspect spliced into a ST connection to one of the e80). Would like to reuse the AP head and the Remote - may do w/o Depth as DSM is cranky about displaying the digits for depth (even after returning for "the fix"). My questions:

I have an NMEA 2000 bus that has AIS and depth and would like to incorporate those and disconnect the DSM (has separate transducer connected to it). Is there a way to do this and still utilize some of these older ST devices (I seem to recall that was an issue in the past)?

I have 2000 to my flybridge station, can I connect a small NG backbone to that with the EVO-1, e80 and p70 head - thus using the 2000 to bridge down to the ev-2000 and the second e80 (and possibly the remote and the old AP head)?

Lastly, I ordered the ev-200 "sail" because I prefer the p70 to the p70r. I am connecting to the existing type 1 pump. There isn't any reason not to go this way for my 8 knot trawler is there?
