If it's a DIY project, you can always make the differential cut as wide as you like. In which case it could work as a TQ or an UQ.
None of these issues seem to be in any way connected to the differential cut. The te-wa being a partial underquilt doesn't make differential quilts too short to use as top quilts, it makes partial quilts too short. You're lumping perceived issues with specific quilts under the banner of all differential quilts. The differential has nothing to do with it.
