Really, I wanna see that. Oh, and no cheating. Don't make those avc encodes intra-only or with otherwise editing-optimized settings, that defies the purpose (since it's going to be a valid editing choice anyway, but it's not what you get out of the box with fansubs or BDs).
I think I'll stick with 1080p, you seem a tad ignorant on the issue of 1080p vs 720p. While certianly not all, a lot of anime is natively rendered out at 1080p. Though for there's almost no 1080p broadcast systems, they're generally 720p or 1080i, so most material is broadcast from a 720p source and upscaled to 1080i. So while television ripped fansubs are capped at 720p, the BDrips can be 1080p, assuming they are rendered out at 1080p. It's certianly not absolute though, I mean hey, FMA: Brotherhood was only rendered at 540p for some silly reason. Then there's all that lovely 90's anime that was mastered on 35mm film, those make for beautiful 1080p transfers. Have you checked out the Lain BDs? If it wasn't for the sake that it was 4:3, you'd think it was animated just this year. It's just a glorious transfer.
Anyway, here you go, this is using Coalgirl's 1080p Blu-Ray of Kanon, the streams were pulled out of the MKVs without any modification, so this is pretty representive of 'any ol' fansub' since it is just that, any ol' fansub. The top five layers are at 15% opacity while the bottom is at 100%, to ensure all six streams need to be rendered simultaniously. There's a 98% CPU spike that you can see the moment I press play on my preview, but it drops and then playback continues with an average of 50%. This is probably it trying to quickly find the last I frame before the start points so it can deliver the first request frame on each track. Though you can see that through the graph yourself.

And please, as soon as you start enabling advanced features in the avc encode, the decoder is gonna fall short because those features were clearly thought for saving space during playback and not for faster than realtime editing. AVC is a lucky format since it specifies how it should be decoded too, but as soon as you wind up loading mpeg-2 or mpeg-4 asp (and maybe vc-1 too, but don't count my word on that because I'm not sure on this one format) encodes you could be getting different looks from a moment to the other since the formats don't specify a bit precise decode so it's all left up to decoders implementations, which might decode differently from what you expect. I don't call that reliable.
You can't just expect any encode to be awesome for editing, especially if it's a fansub encode, which is clearly thought for playback and limiting the required storage space.

Pro-Res isn't used by any cameras however, so to say it's industry standard' for editing is kinda... Wrong. You're gonna edit AVCHD with pro-sumer cameras. NXCAM on low range professional cameras ($5000~) NXCAM is still 4:2:0 AVC, just in a much more flexable standard. XDCAM, MPEG-2 4:2:2, which you'll see in cameras in a 20k-35k range. You're also forgetting DNxHD, which is stock standard on Avid platforms. While Adobe is pro and Apple was once pro, Avid's stuff is still considdered top tier. I've used ProRes though, but only when capturing from an AJA IOHD box. Fun box to play with, BTW. ProRes is most often used for offline proxies, which you'd use since directly editing something like REDCODE RAW would be exceptionally demanding, but just about every camera below the cinema level uses formats that you can edit directly on any decent box.
