If you have the skills and the patience, get it working right (it looks like you did)
and you can always go back in there later and drop in a final gear swap.
Although trust me, once its done and working its hard to go back in.
The fuel savings from going from a stump puller to an airplane can be rather large.
The FE difference on my buick at basically every speed comparing 3 to 4 was massive, at higher speeds I lost about 40%
Spinning that big brick comes at a price, hopefully you mainly want this car as a town hopper and it won't be too bad for that.
If you do venture on the highway get a fuel economy guage of some sort, I would guess 40-50mph will be your sweet spot.
This may be one of those oddball situations where big tires would save fuel, if you want to scrap out the wheelwells and find some light 19" or 20" wheels
Sadly 20" wheels cost more than the final though
Good Luck and keep us posted.
