I'm also thinking about them making both Bryan and Brie champions (if only for a short time) to coincide with their recent pairing with each other on-screen. I had the same thought with Ziggler as WHC and AJ as Diva's Champion earlier in the year as a heel couple both carrying titles but those predictions didn't exactly pan out. If there's any chance of Bryan and Brie having their wedding (obviously not their real one) on Raw, then it'd be neat if both their respective titles were laying on a table beside each other somewhere up on the altar during the wedding ceremony. I know wrestling weddings are generally horrible, but they've always been apart of wrestling and some of them turn out to be pretty entertaining (Savage/Elizabeth, Stephanie/Test, Stephanie/HHH's break up, Kane interrupting the Edge/Lita wedding, etc.)
Imagine they're both about to say I Do and then Randy Orton and The Shield interrupt. The end result is Bryan ends up suffering a massive beat down, and while Brie is in tears over her wedding being ruined, Orton forces himself onto Brie and kisses her while standing over Bryan's unconscious body. Meanwhile, as Brie walks backstage with Bryan (who is being helped out by others), AJ stands there laughing manically at both, both her former beau Bryan and her recent nemesis Brie.
Kind of off-topic, but anyway, in regards to AJ losing the championship or not, I'd probably just prefer they give AJ an almost year long title reign. If she kept the belt all the way to Wrestlemania, that'd make her the longest reigning Diva's Champion of all time.
