Another weird request from the Phoenix motorglider group. We turn off the engine and soar. We want to make the best use of battery power while engine off. We would like to turn off the Skyview and use an external (to the Skyview) Trig transponder to save power. Will we lose engine-on Skyview functionality by doing this?
External trig transponder

I'm not quite understanding the question. Presumably that means you'd be using a full Trig transponder with its own control panel. In that case, you'll definitely also need a separate altitude encoder, as you wouldn't be able to use SkyView's altitude in this scenario. But beyond that, you could restart SkyView when you turn the engine on and any installed options would work fine. The attitude might take a few seconds of straight and level flight to full right itself if powered on in flight, but fundamentally there isn't anything that wouldn't work.

I ran into the same issue when choosing the avionics for my Stemme. I ended up passing on Skyview not because I wanted to but because the power budget was simply not their.
I use a TT22, radio and Butterfly using the wireless on the Butterfly to pass data to a dash mounted IPad. The small solar panel keeps up with this load no problem but would not stand a chance with 36 Ws of SV draw.

With additional batteries I get a few hours max out of Skyview while soaring... Even with many devices powered off (such as ADSB470, servos, etc).
On long flights I sometimes even turn off the XPNDR, but only in class G e.g when running along ridges where radar doesn't see me anyway.
Wish list for Dynon:
1. Dim screen to very low. Dynon removed the ability to dim the screen a whole lot more, please bring it back for us power-challenged customers! Maybe via a setting that allows adjusting 'min. Dim level', high enough by default for power-pilots to not accidentally adjust screen to illegible levels...
2. Low-power Mode for SV e.g. Reducing the refresh rates of things to "glider pace" LOW speeds, or turning off the EMS (but not battery readings!) or similar
3. Maybe a bigger SV backup battery... I did resort to running down that emergency battery to extend my soaring :-?
