Maybe they should just do a minifig series about harry potter. It could include:
-Lockhart (finally flesh-colored)
-Quirrell (same)
-Crabbe (same)
-Goyle (same)
-Cedric Diggory (hufflepuff outfit!)
-Luna (ravenclaw outfit!)
-Cho Chang (same)
-Madame Pomfrey (she's awesome, and anyone having played HP years 1-4 knows how epic her minifig was)
-Fred and George
-Percey
-Madame Sprout (including a mandrake! :D)
-Rita Skeeter
-Death Eater (then we can finally build up an army of them :p)
-Slughorn
-Nearly Headless Nick (!!)
-Fleur Delacour
-...
I am afraid they will be more costly because of license issues... Would be awesome though! :D
