Help Changing Color in Theme and Menus

For the border color of the application I modified the "OFFICE2013WHITE_INI" inside of the Office2013.dll

But I'm stuck on a few things still and really hoping that I missed something in the help on how we can programatically change the theme colors and such instead of editing the dll.

1.) How do  I increase the border width?  I tried extracting the "XTP_IDR_OFFICE2013_STYLE" from the dll, unzipping it, changing the BorderBottom.xaml file to increase the BorderThickness and then using Winzip to zip it back up and insert it back into the dll but no luck.  I was hoping there would be a BorderThickness setting in the ini file for the Frame but that didn't seam to work either.

<Grid>

<Border x:Name='Border' Margin='0,0,0,0' BorderThickness='0,1,0,0' BorderBrush='#FF000000' />

</Grid>

2.) How do we change the font, size, and color of the Caption in the dialog box.  I thought it was probably in the ini file but changing it in the Frame section doesn't make any difference.

3.)  How do we change the highlight backcolor of the items in the main ribbon Quickaccess Menu?

4.) How do we change the highlight backcolor of the items in the drop down menus?

 I'll attach up a VB6 sample I was working on also.
