In your room the L shape created by the bath is going to make things difficult. With your seat by the kitchen there is no way to have a line of sight to the right hand speaker once it is placed by the wall for wall loading.
There are two things to try with Limage placements here. In both cases you will need to have your seat on the wall with the CDs and LP shelving.
Version 1, to start you will need to put up quite a bit of absorption on the wall of the bath where your sub and daybed are. Sofa cushions and such are good enough for the experiment. You may want to put a diffusor or similar absorption on the other side in order to provide symmetry and avoid channel balance shifts with freq.. Though I very much doubt you would get sufficient diffusion to that bathroom wall with a fake ficus, it is worth a try before you pile up absorption on it. The speaker would go on the 40% mark from the back wall (remember that your new Limage front wall is the kitchen) as you are working with the other side of the Limage setup rather than the normal 40% distance from the FRONT wall.
The speakers would be 1 ft from the sidewalls to start and facing forwards tweeters inwards.
Your seat is right at the shelving.
Start with adjusting the distance from the front wall (probably easier to measure from the back wall, since it is more uniform. Then fine tune the gaps to the sidewalls, then see how much toe in you need.
The second setup would use the bathroom wall's corner for wall loading. If you have a bookcase* you can use to extend the bathroom wall then it would have a greater chance of working. If so, your target distance from the Front wall (kitchen wall) is 9-10 ft. Your seat would be at the back wall - about 2 ft into the room and centered to the speakers. That would leave you off center to the room.
Follow the same procedure working on distance to the front wall first then side walls then seating and then toe in.
*The bookcase should have its back to the room and the shelving facing the daybed area. it would be better if you had a wider bookshelf unit - like greater than 3 ft wide.

Thanks for the ideas and the time you spent figuring this out. Unfortunately, the WAF - yes, it is "my" room but it is a virtual "my" :) - probably will not allow me to turn the room around. I guess, I will just have to live with what I got. BTW, I do have absorption on the front wall now and also bass traps in the corner behind the daybed. My main problem is a peak at 45 hz. I can calm it by shutting off the sub but then the there is falloff below 40 hz rather than extending out to 20 hz with the sub. I have tried all sorts of sub placement without much success - probably need a 2nd sub.
I married the perfect woman. The downside is everything that goes wrong is my fault.
No Limage soup for you!
If the speakers are placed 1' from the side walls wouldn't they be too far apart for a solid center sound stage and not hearing individual rt.& left speakers?
In the Limage setup just the opposite happens. You do not hear the individual speakers at all and the space between the speakers just fills up with sound. Limage is counter intuitive but it works in the right room

Not necessarily, I have put the tweeters 16-17 ft apart and still had good center imaging. The Limage positioning scheme uses the sidewall reflections to produce a composite virtual speaker spaced about the width of the room in size.
If you aim your speakers at the sidewalls to bounce the signal off of them then you create a virtual speaker behind the wall and you can see for yourself that center fill remains quite full. Look up "Rooze" for details on how to angle the speakers.
