In short: No.
I've had mixed results with first converting LaTeX to RTF, then importing the RTF into ID, but it totally depends on how "good" the LaTeX writer was. The more complicated the document is and the more 'tricks' the writer used, the smaller is the chance Latex2rtf can do something -- or anything.
The RTF files it generates should be checked anyway, because at times it seems it forgets the odd closing brace.
