It should work fine. My better half and I do this, and I've found typically it's easier if one person gets past the pairing screen on Zwift before the other person wakes up any of their equipment. It's rare, but some times my trainer wants to pair with her dongle or my heart rate monitor might show up on her screen. But otherwise, it works well.

I have dual zwifts. Comment above is right in that 99% of the time then you're fine with pairing as it remembers how you last set it. However, twice we've ended up with one of our resistances being controlled by the other machine which is both frustrating and oddly hard to pin down what's happening at the time.

So we have:-
2 x Neo smart trainers
2 x bikes (actually many, mix of 9,10 and 11 speed, some wth quarq powermeters, some not)
2 x off lease mini desktop pcs (nz$99 each) with basic NZ$100 3D card NZ$99
2 x off lease 22" monitors
1 x 32 inch very basic TV (connected to both PCs)
2 x zwift memberships
2 x ant+ dongles
2 x usb extension cable
8 x powerboard.
2 x fan
2 x RF mouse (so that you can control when sat on the bikes out of reach of the keyboard)
2 x sweat covers for the bikes (you'll need these or be buying a lot of headsets)
2 x towels
Water bottles.

Now some of those things you can do without. The TV we use to watch Netflicks stuff, and having the two PCs means that we don't get confused as to what episode of series we're both up to. Just change the AV Input on the TV to swap depending on who is using it. Equally bellieve that you can now use bluetooth instead of the ANT dongle, but seeing as we've got them I can't see any reason to change.

We both have other devices that could have run zwift, but the dedicated setups just makes it so much easier and crtically quicker to get set up to do a session at 5am. So less excuses for missed sessions.

You don't need this for Zwift connectivity at all. Is there a reason you feel you need this, other than for when she is riding outdoors?

Before you set hers up, write down the Ant+ IDs for all of your devices...PT wheel and HR sensor, any others?

That will make it easier when you go to add her in next to you. As far as I know, Zwift doesn't allow you to name devices, like Garmin head units, so you'll need to be able to recognize your ANT+ id and select it when your Zwift gets creative and picks hers up. It is a super quick check when you boot up in the Devices screen.

I ride next to a buddy a lot. We are both on smart trainers with additional power meters and heart rate straps. Then, add in the multitude of cadence signals coming from various sources. It is an ANT+ signal mess, but in practice, never any issues as long as I do a quick check on bootup.

This ^ My wife and I have the same setup, and I always let her pair up first (her iPad is more flaky than mine for some reason). They seem to mostly remember the devices that connect to them, so it's rarely an issue. We watch movies on the 32" TV centered on the wall between our trainers.

Skip the Garmin, use an old iPhone running Zwift Companion. Second screen gives you all the metrics from the PT somehow.

This is my setup. Television monitor for one rider - zwift running off an iphone with ant+ dongle and transmitting to apple tv. Rider two uses an ipad air 2 on a stand with an ant+ dongle. Like one of the readers suggested write down all of the sensors id’s so you don’t get them crossed up. Both trainers are smart, a kickr core and my rollers are smart insideride rollers which also works great.

Yeah, it would be for riding outside, and I suppose any instances when she is inside but not zwifting.
