So....
Scramble: D F2 D' L2 R' F' R B2 D F U2 L2 B' L' B R' B2 L F' L R' U D B U
Inspection:
FB: F M U' M' U'L' U2 L R' U M U2 M' U2 B
SB: U' R M2 U2 R U2 r' U' r R U R' U' M2 r U R'
CMLL: R U2 R' U' R U2 L' U R' U' L
LSE: U M U M U' M2 U M U2 M' U x' U2 M U2 M
Edit: Does it work? I tried it, but all I got was a bunch of mumbo-jumbo. I don't know whether I just messed up on the moves, or if my solve is incorrect or something.
No it's not. Even the first block doesn't work.
Also, an awefully lot of moves for the first block. Here is a solution with the same colors (assuming you wanted your FB with white bottom, orange left):
x'
F' D' R2 F' r2 R' F' r2 B2 r B'
M' U' R U M U r U2 r' U' R
U' x' D R2 U' R' U R U' R2' D' R U Lw'
U2 M' U' M' U2 M' U M U M' U2 M' U M2 U' M U2 M' U2
But that was a hard first block. I would do:
R' F' M B' U2 R' U M2 F
R2 U R' r' U' R2 U' R' U M' U r
U2 R' D R U' R U R' U R' D' r
U' M' U2 M' U M U2 M2 U M' U2 M2 U2 M
EDIT:
Your LSE was:
U M U M U' M2 U M U2 M' U x' U2 M U2 M
Assuming that is right:
In the end, instead of x' U2 M U2 M, why not M U2 M U2 ?
And:
In the beginning, instead of U M U M, why not U M U M' ? Makes Step 4b easier:
U M U M' U' M' U2 M U M2 U M U2 M U2 M2
or:
U M U M' U' M' U2 M U M2 U M' u2 M' u2
