No, Liquid Glass was stunted from its conception. Any UI designer worth his salt could have pointed out the legibility issues immediately.
The fact that no one (in power) saw a problem with Liquid Glass shows that Jobs was right, that letting the MBAs take the power never works out. And he was wrong for appointing Cook. Remember that Jobs made MacBooks "expensive" (no more expensive or even cheaper than a Vaio or Portege) because he wanted to make great devices with a great UX and UI, which needed a certain level of investment. Jobs loved his users. Cook only loves his shareholders.
