Is there a horizontally mirrored London System, and what is it called? London System is an opening for white, that goes d4, Bf4, e3, Nf3, Nd2, c3. The move order generally doesn't matter too much and there are lots of ways to transpose into this.

However, what I want to know now, is the horizontally mirrored way also a valid system? White will play e4, Bc4, d3, Nc3, Ne2, f3.

(Note this is not the same as the Italian Game because there, the g Knight goes to f3 instead of e2.)

So is this a real system, and if so, what is its name? I'd like to read more about it and its theory. Is it sound? Are there way more traps white has to watch out for?
The answer is no since f3 would never be played there by any strong player as it is weakening, but has no compensating advantages.

That is very close to some virtually-impossible-to-get-to lines in the Bishop's Opening/Vienna game since unlike the queen-pawn London, black has many more ways to throw a wrench into the attempt to play moves without thinking. In an idea world where black cooperates, in the Bishops's, white can try to play for that setup, but would  play f4, which has the advantage of attacking the black center, and opening the f-file.

You can see from this contrived variation that black has many better options, and is not likely to just submit to white's desire to play a London on the kingside. In no case would f3 be good.
