2LLS 2x2 LL Skip method ( can’t think of a good name )
Scramble: R2 F U B’ R2 F U
Step 1. Bar on DL, sort D layer pieces, recognise CP case. All in inspection
U’ F’ R
2. Corner Permutation/ 2-gen reduction/ reduction to RU
This is probably the hardest step.
R2 F R F’ swaps two corners on UF. F RUR’U’ F’ swaps two opposite corners like a yperm.
There are two cases which are a skip. One is solved CP and the other is when the D corners are swapped and U has a diagonal swap.
U2 R2 F R F’
3. Place a oriented corner in D and orient all corners 2 gen (guimond algs), However algs for mirror cases will have to be generated. PM me if you want to help
R’ U R’ U2 R
4. Intuitive everything else
This step should be done with R2 and any U move to preserve corner orientation. Solve the bottom layer and then AUF the top layer.
R2 U
Pros:
Half the solve is 2-gen allowing TPS spam
High chance of LL skip (100%)
Uses inspection time well
Cons:
Lookahead, as there is little direct solving until the end
Hard for beginners
Example solve 2.
R U R2 F U F
R’ B’ U2 R2
U R2 F R F’
R U2 R U’ R
U2 R2 U’ R2

I suppose I should post the idea I ripped off Teoidus and Shadowslice. 2x2GR and 22 had a child and I call it 22GR.
1. CPLine + TL5C setup (optimal under 5 moves, shouldn't be too hard to get close)
2. Conjugated TL5C (around 12 moves, 39 algs; could be all 2gen, but better not 2gen)
So basically you do CPLine as described in
2GR while also putting either (but not both) D corner into the wrong spot, regardless of orientation (so you could put DFR in DBR, or DBR in DFR, and in neither case does the corner need to be oriented any particular way). from there you simply recognize your TL5C case which is quite easy. You have six cases for the D corner and you should know this from inspection, I call them front (for DBR being in DFR) and back (for DFR being in DBR) and o for sticker oriented down, + for sticker oriented forward or backward, and - for sticker oriented to the right, making front +, front -, front o, back +, back -, and back o. And I reiterate that you don't need to look at this, you should know it from inspection. From here you simply look at the orientation of the four corners on U, and which one has the D sticker on it.
The algs themselves are simply TOCLLs which is a subset of TCLL which already exists, however some TCLLs twist the wrong D corner, which is important here, and also a lot are garbage.
Here is the front- set that I put together and genned a little of myself. Should show the general idea of the recognition and also gives an idea of the algs. I don't have all the algs finished and I don't know if I'll finish them any time soon but if someone wants what I have I can get it together.
This is pretty close to an actual L6C method and I think it's far closer to "100% LL skip" than anything proposed before. Plus I think it's actually not even bad, with a fairly competitive move count for only 39 algs.
Edit: one thing I forgot to mention. I haven't played with forcing diag swap instead of solved CP. This would be very similar but none of the algs could be done 2gen. Though they could still end up being better.
