Removing the sound of flem in vocal recording

I doubt its possible to remove the sound of flem from a vocal recording, but has anyone attempted it?

One approach might be to use a spectrum analyzer to try to determine which frequencies are in the flem and try to filter them out. Or another approach might be to use a formant analyzer/generator/filter to "purify" the vowels where the flem is occuring. But I don't think Logic has these tools.

Any suggestions? Plugins?

Thanks.
