Increasing Window Padding in Battle (Specifically with SRD's GUI Core)?

[Cuprite]

I'm wondering if it's possible to increase the window padding of certain menus in battle with SRD's GUI Core. I know you can't do it with the Super Tools Engine, even if it did work with the GUI Core, but there's also nothing in the plugin parameters to change it. The reason I wanna increase it is to potentially make it more mobile-friendly (Kinda like his mobile menu plugin). Is this possible at all or would I need a different plugin?
(Also, the actor command window is gonna be just above the status window, not above the actors' heads, and a lot of stuff here is placeholder, including the lack of a background)

Edit: Added a mockup.

Spoiler: Mockup

Edit 2: Added the PROPER image for the mockup. Lol.

Edit 3: Now that I think about it, I wanna do a similar thing for the item and skill menus, but I'm even less confident about those. :/
