Order editing in Version 1.5.1.3? [solved]

Opencart version: 1.5.1.3

I upgraded my entire website to 1.5.2.1, but some of the modules/plugins I use are not compatible with is - forcing me to downgrade to 1.5.1.3. Until I can get newer versions of these, 2.1 is useless to me.

What has attracted me most to 1.5.2.1 is the order editing. Is there any way to integrate just this into 1.5.1.3?

there is a mod for order editing in 1.5.1.3: http://www.opencart.com/index.php?route ... on_id=3448
