you can convert AAC into Apple Lossless... I just did it. It may depend upon your version of iTunes though.
I had some older files that had been ripped to AAC at 320K as I was seeking a good enough format to rip everything into... Lost the CD but found the older files on an unused hard disc.. Violin! They converted just fine!
The posted bit about loss is true enough though, Re-ripped - converted files, from lossey to lossless is going to be almost entirely unoticable from the lossey (smaller) format.
Re-rip from the orig CD... and use the "error checking" feature as well. There is indeed improvement to the audio going that way... Error checking + lossless = Better!
The above applies only to those CD's that you rip this way... downloaded 128/256 K etc., AAC can't be improved, just fresh rips direct to a lossless codec.
