“Yes, I have current coverage on this phone. iPhone SE was available through the Apple Store in January, had one in my bag to buy for my wife. Apple shows I still have full coverage, accident, theft and loss, hardware service, express replacement, and 24/7 priority access.”

Note:
Your wife should have her own Apple Account; you should never share an Apple Account amongst one another.
So,…
Transfer this, as if you were to Sell it:
Your only option would be to transfer YOUR iPhone to your wife’s Apple Account, as if you were to sell it. So, reset this to factory settings by signing out of iCloud. Once reset, transfer the AppleCare to her Apple Account as the new owner of it. Once transferred, she can then use Quick Start to transfer her old phone to this iPhone of hers.
Once Transferred —Get a New iPhone:
But, if you go about purchasing a new iPhone, Apple’s not going to sell you a discontinued model. So, she’ll have the model she desires, but you’re just not going to have the option of having same model as this one you gave her.
