Good, short, high Heroic & low Paragon Tier adventures to add to an ongoing campaign?

[S'mon]

On Monday my 9th level PC group got trashed by an 8th level adventure (Dungeon Delve #8) featuring an 11th level dragon, and it occurs to me that I need to give them the opportunity to take on some lower-level threats, but I'm a bit short of suitable adventures they might take on in the high Heroic to low Paragon area.

Here's what I currently have available/planned:

Heroic Tier
Dungeon Delve #5: designed for 5th level PCs, but would give my group a bit of a breather after the near-TPK last time.
Dungeon Crawl Classics - Tomb of the Blind God: for 8th level PCs.
Dungeon Delve #9 - designed for 9th level PCs, so prob too tough for them.

I also have some suitable DCCs for 1st-4th level, but they'd need a lot of adjustment or let them be really easy.

Paragon Tier
DD # 11
DD # 12
Steading of the Hill Giant Chief - for 12th-13th level PCs
DD #13
DD #14
P2 Demon Queen's Enclave - for 14th-16th level PCs

Assuming I may need to run stuff written for PCs 1-2 levels lower, I should be ok once the PCs reach around 13th level, but I don't think I have enough to get them from 9th to 12th. So I was wondering if ENW could suggest me some good 4e adventures I could use? The setting is Forgotten Realms' Gray Vale, a northern temperate land with forest, mountains and moorland, no big cities and no sea coast. Near-surface Underdark would be ok. Adventures can be from any source, I either have it or can get hold of it.

Thanks!

Here at dungeonmastering.com they list a whole heap of free adventures (for 4E and 3E). Three of them are 4E adventures from Dungeon Magazine that fall within your level range:

The Last Breaths of Ashenport (5-7)
Sleeper in the Tomb of Dreams (8)
Massacre at Fort Dolor (8)

I've never run Sleeper or Massacre, but I absolutely love The Last Breaths of Ashenport. Great adventure in my opinion. Probably easy to bump up in level just by adding an extra monster to several encounters.

I have pretty good write ups from my old campaign in PDF format if you're interested. Not sure if you're doing dungeon of the week style or an ongoing campaign, but here are the adventures I could share that are around 8th level:

6. The Drowned Citadel - A six room dungeon crawl through a haunted partially submerged mountain citadel, with a fun intro encounter and nasty capstone encounter to gain a lost magic crown.

7. A Rose for the King - Tournament-based adventure with the overarching goal of identifying a knight marked for death, then preventing assassination of said knight.

8. Illusions of Grandeur - The PCs invade a ruined eladrin tower at the center of a lake which has been taken over by a traitorous fey, facing five encounters until they face the traitor Lady Ghaulinde.

These were written for a large (6-7) group of players who met every 2-4 weeks, so they're very condensed and have some "jazz oddities" that you'd need to interpret ,but we had lots of fun with 'em.
