To answer the question, yes it is possible, but White should keep a slight advantage. For the Guimard, see Tzermiadianos's repertoire book, and for the Hecht-Reefshlager, 4.Nf3 Nf6 5.e5 Ne4 6.Bd3 Bb4 7.Bd2 Nd2 8.Qd2 f6 9.a3 is known to give White a slight edge.
If the above mentioned line is Black´s biggest problem, the Hecht-Reefschläger is really looking good, since recently deviating with 8....Bd7 was analysed in updates by Wei Ming and Macdonald. After 8.a3 Black has three lines (8....Bxc3; Be7; and maybe even Ba5) at his choice which all were reviewed well by the chesspub authors and with the exception of Ba5 score well for Black. It would be surprising if not at least one of them will proof reliable in the long run.
The practical value of the Hecht-Reefschläger as a part of a french repertoire in the ELO - range 1400 - 2000, where most my opponents can be found, cannot be underlined enough. After years of playing the French, the opening as a whole in my opinion is the most effective weapon on this level of play, if you want to fight for an opening advantage as Black. White e4-players facing it are quite annoyed to be kept out there favourite open games or Sicilians. Very few like to play the French as White, especially the more theoretical lines, so opening play often is very easy for Black:
10 % of the games feature some kind of 2.d3/b3/Nf3 variations
30 % are toothless exchange systems
30 % are advance systems, which are OK for White, if he knows what to do. Most of the time he does not know as soon as move 6, and so I won more than a couple of games because White simply forgot to defend d4 sufficiently or tried to eliminate some pressure with Bb5, allowing Black to get rid of his bad bishop and play a much better and easy to handle endgame
15 % are Tarrasch -Systems, where Black has a wide choice of more or less theoretical systems and therefore an easy preparation.
At last, only 15% are 3.Sc3 - systems. Why use mainlines here since White almost never goes for winawer mainlines (4.Ne2 or 5. Qg4 are quite popular) and after 3.Sc3 Sf6 Black has to prepare a lot of different variations?
So, from a practical point of view, on this level 3.Sc3 Sc6 is a dangerous surprise weapon, minimizings preparation while maximizing the chance of White being completely unprepared and following general formulas not working in the specific varation.
