The Weddle conversion kit has a taller r&p so even with reusing the 4
speed 4th as the new 5th you would still get lower rpms on the highway
in top gear. Depending on your engine and van model you may not be able
to pull a top gear much taller than that as much as you might hope. In
contrast Don's old 5 speed from 83 diesel vans has a very much lower r&p
set so even though it uses a 5th much taller than the wbx 4th he still
runs slightly more rpm in top gear with it than with a wbx 4 speed.

I do wonder what Weddle thinks people will do for a shifter. Another
company has been selling 5 speeds with a modified lock-out guide to go
in the Vanagon 4 speed shift box to replace the one welded in there at
the factory.

The AAP 5 speed has the tallest overall top gear of the various models
though never used in USA/CA Vanagons.
