I would highly recommend Increased Trait Count to allow you to select these as well as the base game traits.

Anything that edits the Concealment skill.
This does not touch the base skills, with the exception of Concealment, so depending on where this and the conflicting mod is in your load order, you'll either have my Concealment (if below) or their Concealment (if above).
Obviously if you have a conflicting skill mod where you want their benefits over mine, you can place that mod below mine in the load order and it will overwrite my own changes but will still keep my background and traits there.
