I have a halogen lamp from IKEA with a 120V to 12V transformer.
The rectifier (presumably) has failed and the transformer is

Can I wire in a generic rectifier to the output side to solve the
problem?

Thanks for any suggestions.

Why do you think the rectifier EXISTS?
The lamp doesn't care whether it's ac or dc. *At
least the first order effects don't care.
It should be a tiny bit happier with AC.

Somebody should know how the redeposition of tungsten from the halogen
interacts with the different notching patterns created by DC and AC
currents.
