That's pretty much as close as I can get mine due to the shape of my ceiling. They're a touch over an inch from the angled part between the knee walls and the ceiling (must have a proper name).
At that distance from the sides, I run out of speaker cable 103" off the front wall. That puts the plane which contains my ears 147" from the speakers. Measuring in an oblique angle from the center of each speaker to the center of my head reads 157". The center of my head to the back wall is 155".
The subs are 18" off the floor on ASC sub traps and the center of each sub is 55" forward of each 3.7 - they have radiators on three sides. That puts the subs 157" off the front wall at center, which is another 249" to the rear wall.
The room has a rug covering absorptive foam (which fills the cavity to the window) in the center of the front wall. That is flanked by Q'fusors and the corners are filled with ASC bass traps - and, now, a little forest of fake trees. There are three 2'x4'x2" fabric-wrapped fiberglass panels (with beveled edges) on each side wall in the center of the room. The doors in the back of the room have an arrangement of suede wrapped 12"x12"x1" fiberglass panels glued to them. Each back corner has an 11" (diameter) ASC bass trap.
I think that pretty much wraps up the lay of the land. ;-)
I can't avoid the opportunity to express an enthusiasm regarding the HK/Limage arrangement which hasn't diminished at all.

(Grand) Wazoo:So based on your room dimensions, you have your speakers out about 25% out into your room. The "classic" HK/Limage setup seems to have them out about 40% out - in your room, that would be about 161" out from the front wall.
My experience has been (attested to by others here) is that the benefit afforded by high quality interconnects is dwarfed by getting room placement right. So here is my suggestion: get some longer interconnects to connect your preamp to amplifier cluster, then move out both the speakers and amplifiers out the full 161" out. And see if that makes any qualitative improvement. The worst thing will be that you got some exercise ;-) and spent a few bucks on cheap interconnects at Rat Shack. Heck, you might get your $$ back from Rat Shack even. I'm dying to see if the 40% "rule" is really that, or if it is so room dependent that in some rooms (like yours) 25% is all that's necessary.
And that 35"... does that mean the edge of your speaker is only a couple of inches away from the wall, and the ribbons are inside?

There is a matter of absolute distances, which are ample in Waz' room, which is unusually long. The standard "recipe" is for rooms with L/W ratios in the 1.2 to 1.7-8 range. For longer rooms the main point is to get the bounce off the front wall delayed so it is perceived as reverberant field info. Though the "standard" observation is that 5' is enough, I found that 8' is much better, and further out from that somewhat better yet.
There are other issues besides the length of my speaker cables. My listening position is rather anchored at 38% off the rear wall - with a riser behind the front row of seats. My subs are essentially where the 40% rule would put the Maggies. I'd be sitting less than 100" from the plane of the speakers - well, I could sit on the sofa.
Each outside edge is 15" off its respective side wall - limited by ceiling shape.
I hate to be resistant to experimentation, but I don't think my attempting the 40% placement is in the cards. When I ordered my speaker cables, I added a bit of wiggle room to the Cardas placement calculation. In retrospect, a little more wiggle room would have been a good idea, but I had no idea at the time. Regardless, there are other constraints that complicate the issue.
