The art of sequencing an album is lost with the advent of the CD which pushed artists to make longer albums (not good) with the "hits" early in the tracklist. Some great sequenced Rock albums in the CD era (OK Computer, Is This It) act as throwbacks to the vinyl album era but an album from the era that could be improved is The Kinks Are The Village Green Preservation Society. Usually considered their masterpiece (not to me, that's the next one) the tracklist lays all of the fey, "relatively" weaker cuts at the end - and then closes with a really great one "People Take Pictures of Each Other" - it's just off to me.
Include those songs with side 1 (which is far better) and it seems more of a cohesive whole, then end side 2 with Big Sky - a big statement - and end side one with "People Take Pictures of Each Other" ..........then I couldn't say "great album that runs out of steam at the end" as I often do
I would add the singles to some of the mid period Beatles albums. Sgt. Pepper actually might be the best album of all time if you axed some of the lesser songs in favor of Strawberry Fields/Penny Lane/I Am the Walrus. Revolver would also have a more psych/rock feel if you removed a couple songs and replaced them with Rain and Paperback Writer.
High and Dry might be the worst thing Radiohead ever recorded, even including the Pablo Honey post-grunge power ballads. It was 100% filler that they only recorded because EMI insisted they add one more song to The Bends. It would have been better just without that track or with one of the many excellent b-sides from that period added as the extra songs instead. I'm nott sure why they didn't just do that instead of hacking something out.
Then there's the multitude of double albums you could make better by condensing to a single disc, but I don't think that exactly counts.
