If I had to guess....(under the assumption Ferrero is in)
I honestly dont even have a clue where his ranking is, but if he were not to get direct, he would get one instead of Gaudio or Recouderc.
JCF needs one more win in Casablanca to get a direct entry for RG. He'd be 109th he if loses tomorrow, which might no be enough (depends how many withdrawals and Protected entries there will be.)
For french wild card i think Mannarino (1 challenger final +20yrs old), Ouanna (1 challenger won, 23 yrs old next week) and Recouderc (24 yrs, improving recently) will get one for sure.
Patience is getting a bit old and has not won a main draw match this year so far.
Gaudio will get one if he decides to come. Hopefully he will be able to play (and win) some matches before RG.
Sidorenko (21) is getting decent results so i think he will be there too.
So my guess is Tomic, Isner ( Odesnik will have a direct entry), Mannarino, Ouanna, Gaudio, Recouderc, Sidorenko, Montcourt, Mahut, Ferrero or Eysseric or Patience or De chaunac or ERV.
