Org agenda structure sizing

So the agenda is split into sections with headers. These can be customized using org-agenda-overriding-header and have the face org-agenda-structure. I would very much like these headers to be the size of modus-themes-scale-5 or at least customizable to that size.

I'm sure I could jerry rig up a local solution that does exactly what I want, but since they're literally called "headers" I thought maybe some other folk would like this change too.

Also, a little side note (that got kinda long as I started writing), I can barely tell the difference between fg-special-warm and fg-main. I think the idea is that it's nice for some things to have very subtle distinctions, but in my opinion org-agenda-calendar-event and org-scheduled should have big distinctions. "Section 8.3 Deadlines and Scheduling" of the org manual says you schedule something when you want to start working, and the org event is for something that is happening. I use scheduled things to say: "Hey Morgan! You really should be doing something at that time!" and events to say: "There's a thing happening. Do whatever you feel like". So I made my scheduled face be magenta so it really stands out. I'm no expert here and I already have a solution, but I thought I'd let you know.

P.S. Just updated to the latest 1.1.1 and turned all the variables on. It's absolutley beautiful. I really love it. I love it so much I decided to throw out my org-beautify config because you made my emacs even more beautiful than org-beautify could. The agenda header sizing is the only thing I miss from org-beautify.
