Trim, Fit, and Canvas size Script

Hello everyone, I've been racking my brain trying to figure this out. I have many images with a product cut out on a pure white background and I need to figure out how to get it to fix on a canvas with a ratio of 2000/1778 with the product fitting either horizontally or vertically. if the product is larger than 2000/1778 the action I created works perfectly but, if it is smaller it leaves too much room either on the top or sides. the action I created goes like this:

CROP

Trim

> based on: top left pixel color

>with Trim Top

>with Trim Bottom

>with Trim Left

>with Trim Right

Fit Image

>height: 1778 pixels

>width: 2000 pixels

>With Don't Enlarge

If

>current document is landscape

>Then Play Action: action "horiz crop"

>Else play Action: action "vertical crop"

Horiz crop

>Canvas Size

     > Height: 1778 pixels

     >vertical: bottom

     >Extension Color: background color

Vertical Crop

>Canvas Size

     >Width: 2000 pixels

     >Horizontal: center

     >Extension Color: background color

If the images are larger than 2000/1778 all goes well and they come out like this (Black border only used to distinguish it from background):

if they are smaller they come out like this (Black border only used to distinguish it from background):

Any help anyone could give me would be greatly appreciated.
