No too much work.
Wii U = old impossible to code for CPU (IBM arch) + old AMD GPU arch.
Nintendo Switch = Arm cpu arch + Nvidia gpu arch.
Maybe some older Wii U games will be ported to the NX, if they still have the source files, and they where made in programs that can also easily run on the NX.
But the other way around? I seriously doubt it. Dont expect any NX games to show up on the Wii U.
