A new move order?

There are quite a lot of threads on here of people claiming to have invented their own openings, most of which aren't sound, but I think I may have discovered an interesting move order for Stonewall and Classical Dutch players which doesn't seem to be known, although there are games in which it has been played though not necessarily for this purpose.

Background: I play the Stonewall Dutch as black, but the trouble with the Stonewall is that it's not ideal if white has played 1.Nf3, so hence I was looking for something else to play. However, the trouble is that against the various options black has there are move order tricks for white to take black out of his repertoire, for example 1.Nf3 d5 2.d4. Black is also not able to play the Symmetrical English directly due to 1.Nf3 c5 2.e4, which is unacceptable if black is not a Sicilian player. However, there is one move order which allows black to enter the Symmetrical English regardless of what he plays against 1.e4:

The 1...e6 move order for the Dutch is known, but playing 1.d4 e6 requires black to be a French player, and also is for a different purpose (avoiding the Anti-Dutch lines). While after 1.Nf3 e6 white can enter a French with 2.e4, all of the critical lines are now excluded. The main thing to be aware of is what to do if white tries to trick you into an Advance French:

Does anyone have any opinions on this? I hope this helps someone out
