Yes it is possible in france (I had one) but you have to be very stubborn determined about it.

If you put your postcode/department into this site you can get a listing of local independent midwives. They can do all your antental care (whatever the doctors tell you). A few if them will do home births, the rest attend births in hospital. If you want to have a water birth it may need to be a home birth, as few hospitals will support this.
As there aren't that many midwives who do home birth you may have to phone more widely to find one - the one I eventually found was over an hour away from me in another department! But she was willing to cover a wider area.
I would phone around your local midwives and have a chat about what you want. If you don't get a good feeling call someone else. Ignore anyone who tells you what you can or can't do - they are not the kind of person you want around when giving birth anyway.

I phoned these guys and they were very helpful but not in your area so I don't know whether they will know anyone around you.
One thing to bear in mind is that you have to send in your declaration de grosesse by about 13 weeks to get the benefits going - your midwife can sort that out for you. Other than that there is no huge rush - your nuchal will be at about 12 weeks but you shouldn't experience any delay getting an appointment (we had our first appointment within the week and that was in May which seems to be one continuous bank holiday in France.
Feel free to get in touch for any questions/support/if you need a rant - having been through it I'll be sympathetic!
