I clean the case on every build I do, no extra cost. WPC for the essentials(3-4-output shaft) is about $200, the whole box is $500.

1st and 2nd include the input shaft, so I wouldn’t bother modifying those, 3rd and 4th can be manipulated in almost any way you like...and 5th gear can be lengthened to accommodate a more aggressive final drive if you choose(requires a new output shaft and ring gear).

My standard fee is $600 labor for the build, and that includes a spec sheet and certification label.

So, the way to eliminate the huge RPM drop between 1-2 and 2-3 is through a shortened final drive?

And to get me back to my super lower cruising RPM, a really tall 5th gear is the solution?

Would I end up right back where I am now for cruising RPM?. Even though this car gets sporadic use (its only got 15,000 total miles) , that use can sometimes include 14hrs in a day of highway driving while on trips. Its for this reason that I'm trying to have my cake and eat it to.
