Notice how each 'brand' is the same thing over and over.. same formula.

Shoulda/woulda/coulda's (sorry Vince but maybe taking a year off to bounce grandkids on your lap might do you and the product a bit of good):

ECW:
GM shouldn't have been Teddy Long..  Teddy seems to have the jive to do some serious commentary!
GM Foley (never should have done commentary)

Change the show line up/format: One commentator and One backstage person that we would see very little of.  Tazz would've been a great 'voice of ECW'.  The commentator would stay close to the TitanTron entrance doing his commentary and have wrestlers cut live promos in front of the audience there. Cut all locker room skits.

RAW:
Keep it the same.  Jerry "hey look at that" Lawler needs JR.  That formula works and is money.  Keep all the stuff, skits, vinettes, commentary at ringside et al.  Do not PG the show.

Smackdown:
A new network, a new show!
what?!?! but..
New Show!!!
Am I crazy.. YES.. Welcome to WCW Smackdown!
(huh?  why?.. cuz you will have a splinter 'Heat' style show called WCW Thunder in syndication with matches that don't make WCW Smackdown, another machine to gamble on lesser knowns while recapping an already canned Smackdown)

Format: Three Commentators!  AND a perm Spanish Announcer's table (think syndication in Spanish speaking countries that hasn't worked out that well.. until NOW).
This is the extreme family friendly show, with a hint of double entendre for adults to watch with kids.

A fresh style with good vs evil, rockers, gimmicks, heavy on the cruiserweights.  A brand that doesn't mix with any of the others as the package is for non-cable, family and syndication.  This would expand WWE instead of running the same hamster wheel with the cookie cutter technique that hasn't changed since back when they had no competitors.
