If I ran the Seattle AM/FM market, here's what it would look like
AM
570: KVI (Oldies)
No 630...have enough religious stations here, even though I am a Christian
710: KIRO (News)
770: KTTH would go back to KXA and likely be talk or another music format
No 820
850: Go back to KHHO's Top 40 format in the 70s, or try KH2O News/Talk again.
880: KIXI stays the same
950: KJR (Channel 95 brought back)
1000: KOMO (All-News, like it is now)
No 1050
1090 would go back to KING and likely News/Talk like it was back in the 80s
1150's call would be KEZX (wasn't it?)
No 1210
Don't need KWYZ/KSUH, only for the Korean immigrants
1250: KKFX and back to the old early 80s style format
1300: KMPS, probably simulcasting 94.1 like they did a long time ago
No 1360
1380: KRKO (News for Snohomish County)
1460: KARR as a Mexican and not Harold Camping's end of the world predictions, as you know, he failed several years ago with that
1590: KZOK and Z-Rock brought back
1600: Take over KVRI and change it down south back to K-JET!
FM
92.5 back to Classy KLSY
93.3 adds more 80s/90s stuff to the hip hop
94.1 stays the same
94.9 stays the same
95.7 stays the same, but bring back the Lost 45s!
96.5 revive KXRX and put Crow & West (if they are still around) back on
97.3 revive KBSG
98.1 stays the same
98.9 revive Smooth Jazz! Only my opinion, but the new format is a clone of KPLZ/KMTT combined, as well as maybe Alice @ 97.3 in SF.
99.9 say bye bye to all talk 18 hrs a day, go back to 24 hr music KISW
100.7 stays the same
101.5 stays the same, but try more of a Rhymthic AC
102.5 stays the same
103.7 stays the same
104.5 will still be looking for a buyer

105.3 stays the same but a little more religious preaching, especially at church hours Sundays. Remember when they were KBIQ and served "From Vancouver (BC) to Vancouver (WA)"?
106.1 stays the same for younger listeners so that they can hear Rihanna's "Only Girl in The World" for the 20th time
106.9 stays the same
107.7 revives as KRAB (bring back that weird world music they used to play!)
