Canals from Med for yacht drawing 1.8m

I should be most grateful to from anyone who has recently taken the route to Le Havre via ;- R Rhone, R Saone, canal Marne a la Saone,C. lateral de la Marne, R Yonne ,R Seine.

Mainly I am uncertain whether this is possible for a !.8m craft and if so, the best time of year to go.

I am currently moored for the summer in Barcelona.
