Ok... I'm able to get everything... Here's how I did it:

# Extract the [0] file from exe
7z x qt-installer.exe -t* -i![0] -y

# Extract only embedded 7z files from [0]
7z x [0] -t# -i!*.7z -y

# Extract content from all 7z files
7z x 2.7z -ai!*.7z -y

And of course, delete the files left behind ([0], *.7z)
