Yes, but the Marshal's mutinied because it was better for France for Napoleon to come to terms, Marmont's surrender persuaded Napoleon to do so. Had he refused Ney made it quite clear, the army would not follow him.
The marshals mutinied because they thought they couldn't win. Napoleon had already abdicated before Marmont's treason, not after. I don't think the army would have followed Ney, they would have followed Napoleon and were prepared to do so when Napoleon abdicated.
And Net, et al, did not want the Bourbons back but wanted a regency for Napoleon II. Marmont's treason ruined that idea and made Marmont a pariah as well as a traitor. Again, see Caulaincourt's memoirs.
