Question: Flights leave at similar times so we could both get through TSA with our own tickets. Could we then swap tickets before the gate? How strict are they on this? Think the gate attendant even looks at the name? I know they do not recheck ID for domestic flights.
Rant: To bad I didn't marry a guy, then I wouldn't even have to ask this question

The TSA sometimes does gate checks, a small minority of which include ID checks even for domestic flights.
Gate agents may or may not notice any difference between the gender-connected title or name and the perceived gender of the passenger. But sometimes they may ask for ID (very rare as that is for domestic flights).
If there are flight disruptions, your plan could easily come undone with varying degrees of consequences and problems arising thereafter.
And don't you think it makes sense for you to use your employer's resources in the way the employer intended? Misappropriation of an employer's resources is what this could be considered, and I would suggest not to go down that road.
Instead of public transit at the destination, a rental car, taxi or uber/lyft/car service isn't an option? How much distance is there between your ticketed destination and her ticketed destination? Maybe you can drive to pick her up?
