Yes, that approach will work to some degree.  If you get work by this method to create a properly tagged corpus, we can then turn around and use that as a training corpus for French.

As you suggest, i'll start with a use the english MEGRASP function to annote the grammatical relations of some transcripts : it will be a usefull base (basic sentences structures of french and english being quite similar) for then correcting the tagging by following the manual instructions.

You can read chapter 11 of the MOR manual to understand which grammatical relations would have to be tagged.  I would say that creating a reasonable training corpus for French would take about 10 days of solid work.  It could be a bit faster if one uses the trick of starting by using the English MOR.
