Of course it's not that simple but wouldn't be surprised if that was
part of Schempp-Hirth's thinking when developing the Quintus. The
original Antares in 18m and 20m comes to mind as an example of inner
panel manipulation at the wingroot

The Quintus wing is an Antares 23 wing. It is built at
Lange in the Antares modular mold, which has different
inboard sections for the 18m, 20m, and 23m wings.
So, there is ALREADY an 18m wing in production for
the "18m version of Quintus" - Its the Antares 18S/18T.

Now we just need to get some top pilots flying them...

Hope that clears up the confusion,
