Is this any good?
I mean for black. There's no way I'd actually do something like that. I mainly play as black, so that's all you really need to look at. U know that too
Well there is something fun that's related and sound. It's what I call the Alphabet System in the Anderssen opening. It goes 1. a3 2. b3 3. c3 4. d3 5. e3 and irrespective of what black plays (for the most part) this is a good system. Magnus has even opened with something like d4-e4-c4-a4-b4 to create this tabletop structure.
But your system above, no, that's like trying to ward off an alien invasion by wrapping the earth in tinfoil. The pieces are much stronger.
Black has for example 6...Nxe4 and together with Nc6-Ne7-Nf5 and the queen, the pressure on white's e1-h4 diagonal will be too much. You are beat in under 20 moves.
