Taller Header & Different Title for blog pages & blog archives

Wes,

Fantastic theme – congratulations on a great job.

Wanted to get your opinion on the best approach to accomplish a goal.

I want my website to have three distinct sections – leveraging everything the Optimal Theme has to offer (clean design, responsive, etc.)

I want to keep the thin Secondary Navigation bar at the top every page and keep everything under the same parent URL with similar look/feel/navigation, but with each section having a unique Header & Title. (I know I can change the column/sidebar layout  for the individual Pages & Posts)

The plan is for everything else to be accomplished within the standard capabilities of the theme & Genesis framework to keep unified analytics, newsletter registration, social media integration, comment management, etc. consolidated.
The defining characteristics of the three sections are:
A) Company Pages

URL: http://www.example.com

Title: Company Name | Description: Company Description
Design: Home Page similar to Optimal Demo home page with Slider, multi column footer, etc.

Header Height: 100px

Content: WordPress Pages (as opposed to Posts)

Page Format: 2 Column, Left Sidebar

Includes Portfolio Page with Various Presentations (www.example.com/presentations)

B) Blog
URL: http://www.example.com/blog

Title: An Awesome Blog Title | Description: An Awesome Blog Description

Content Type = WordPress Posts | Category = Blog

Design: Multiple full width (960px) header images with random rotation (no slider), same multi-column footer as main Company pages.

Header Height: 415px

Content: WordPress Posts (as opposed to Pages)

Page Format: 2 Column, Right Sidebar

Single Posts & Blog Archives – share same header as main Blog page

C) Quote of the Day

URL: http://www.example.com/quotes

Title: Quote of the Day Title | Description: Description of Quote of the Day

Content Type = WordPress Posts | Category = Quotes

Design:  Single header image (no slider.) Simple archive-style layout, same multi-column footer as other sections.

Header Height: 100px

Content: WordPress Posts (as opposed to Pages)

Page Format: 1 Column, Full Width

Single Quotes & Quote Archives (for example, by author) – Share same header as Main Quotes page

Fundamentally, I believe the answer may be to have a custom home page, but with dynamic headers/titles that will change based on the category (none, blog or quote.)

Any suggestions, code you can provide would be extremely helpful.

A Network/Multi-site WordPress installation will not work because “blog” is a protected term and I don’t want to set up redirects for my existing 170 blog posts and associated links for images, etc.

I will cross-post this on the StudioPress/Optimal Community  and appfinite Optimal Theme support forums to see what the community can also offer in the way of suggestions.
