Ignoring scale and any local requirements, yes, that's a valid trap and vent.
Be aware that local inspectors can be touchy about t-junctions. You might need a rounded or angled junction here so the new drain doesn't splash directly against the opposite side of the vent.
Cool - thank you…
Do you happen to know why so many diagrams seem to have loops? (like this):
Without that extra loop, it's possible that flushing the toilet will suck the water out of your sink trap.
I know absolutely nothing about professional plumbing, but wouldn't that sink loop need to be there to act as a drain and vent for the sink? I don't think the main vent stack would work for that without it
