Thankfully I haven't seen any I-Beams for this floor plan in any finished variants I've walked through, but I have seen the support pole as marked on the attachment in post 8. I'll be adamant about knowing placements.
Is the 26.5' from the very front wall to the rear wall, or from the screen wall to the rear wall? I have a bit over 21 1/2' (oops before!) from screen wall to rear wall. I can't exactly tell scale, but if yours is from front wall to rear wall, and the screen wall is 2 1/2' from the front wall, then really you are looking at 24' of room.
If you are looking at upright chairs, then probably more do-able. If you are looking at reclining chairs, that will be tough. I think for reclining chairs the recommendation is 6 1/2' minimum space between rows, ideally 7'... but let's say 6 1/2', if you have seat backs of the first row at 9', then you are looking at 15 1/2', and 22', so, not impossible by any means... and if you go with a more shallow screen wall, certainly more doable.
I guess it partly depends on how far back your front row is... mine is about 9' from my screen, which is a 132" wide 2.35:1 screen. This makes the screen big enough for the 2nd row & bar, and a tad big for the 1st row - but I prefer the 1st row to the 2nd row.
Now that I look at your attachment closer, looks like the Sump pump is out of the way, and the support column is out of the way (although, I would have thought you would only need the support column if you had an I-beam... )...
In terms of width of seating, I see your notes about 8 - 8.5'. That would give you call it 3+' on each side of the aisles, which is great... but not required. I think I have about 2 1/2 feet, and don't perceive it to be the cramped... in which case with a 15' wide room, you could push 10' wide seating.
