Honestly, I do think it could work if handled properly. It's not like most people watching Toonami aren't already familiar with One Piece.
Being familiar with something doesn't mean you're caught up with it, or even checked it out at all.
I understand the legit reasons for defending why One Piece should start at episode 1, but at this point I feel like it's a bit late to do so at a once a week pace.
We'd all rather have multiple airings a week, but it works for "Bleach" and "Naruto". Why would it be a problem with "One Piece"?
It feels like a bit of a risk to have to wait 4 more years for episodes that haven't aired on US TV before, regardless of how butchered the 4Kids dub was.
Why? If the DVDs come at the same pace they've been going down, you won't have to wait 4 years to get to the new stuff. In general the people that want to start on Toonami at season 4, generally speaking from my observations, have already seen or have enough exposure to those first three seasons. They've seen the DVDs, the legal stream, they know it's out there. So why is it a problem for taking a while to get to the current point if the venue is already well-established for the people in the know?
The newer episodes need more attention, especially if we want to see FUNimation continue to dub past where they are now and it could increase DVD sales for those episodes.
Big disagree, and now to my main point. The newer episodes don't need more attention, they're getting plenty of attention from the people that care about them the most, the hardcore fans. And for T.V., obviously I think the focus should be from the beginning. Why you ask? Not starting with a clean fresh slate defeats the whole purpose of putting it on T.V.
Why do you think it's such a big deal for a popular anime to air on a popular cable channel? It's not just to make more money, and not just for the ratings. It's exposure. Putting anime out there in a venue where it will potentially reach people that don't usually watch anime, or don't usually go on forums like this or Crunchyroll or buy DVDs or what have you, creates new fans.
The anime industry is already sustaining itself with its core fanbase and structure, but when you're putting something in a new outlet that reaches a broader audience, why wouldn't you want to focus on making new fans? Why would you make another venue just serves the exact same purpose of what's already out there? That's the whole point, and the logical way to introduce people to "One Piece" is at the beginning.
And in all honesty, for a lot of the people who watch "Naruto" and "Bleach" on Toonami this might be their first time watching "One Piece", and if not that their first time seeing something other than the 4Kids dub. Also for those people that were just watching it on Toonami back in the day, it's been five years since then, might as well start off fresh. Also with the rate FUNimation's been planning to dub the series (season 5 announced way before this announcement and way before season 4 is done getting released), it doesn't seem like there's a problem continuing the dub regardless of ending up on Toonami or not. And exposure is exposure, the DVD sales will increase on the basis of airing on T.V. Airing earlier episodes will not alienate viewers and in turn it won't be an issue for increasing DVD sales.
I'll still support One Piece and Toonami by watching either way, but there really is a good argument for both sides.
