This is a common question. Theoretically, what you propose could work but it isn't recommended.

Drawing the power directly from the battery helps isolate the vehicle's expensive to repair electrical system from any short circuits that could occur in the trailer wiring, which is why the trailer harness manufacturers recommend installing a direct battery connection.

I've linked to the installation instructions for the Curt # C56218 trailer wiring harness, an install video and a help article that provides some advice on how to route the 12-v feed to the battery.
