There IS a reason why Fujino specifically said "as long as it doesn't affect the plot" regarding suggestions he will accept, if they're anything that goes against his planned endings, which he already has set, he won't do them so all of them may as well be falling in deaf ears

(I already saw one in english even that had several requests that completely ignored the setting and just wrote endings they wanted lol)
1-Yui is literally an AI within a virtual world, backpain isn't an issue for, and thinking of 'realistic breasts sizes' in anime is already moot point anyway, Suguha canonically has no issues despite having like a 90 cm bust since she was 15 (And that with SAO being a mostly 'realistic' world when it comes to female sizes, unlike many modern age harem and even shonen anime do with most of the girls having tits the size of their heads lol), and there is no explanation beyond 'she does kendo', you can bet Yui wouldn't have back pain even if Fujino cared for those details XD
2-Outfit is wedding-inspired a bit for sure, but also princess-like, so is probably a midway there, and she has been quite blatant in that she wants Inoda to fuck her for a couple updates now really, she just hasn't straight-up said it.
3-There is NO announcement from Fujino where he specifically has said at all that the update will be at the end of november, someone just randomly said it here thinking Fujino had. It's very likely it won't be done for early the next month but I don't think it would be later than one or 2 weeks into november, the biggest part of what Fujino is still missing are the actual CGs for H-scenes after all and all of them will be Asuna, maybe Yui if he decides to finally give her a sex scene on this one though not likely yet, so once he gets going with them he will probably clear them relatively fast with just one character involved.
