If you plan for it, you might be okay depending on how far into the chassis the totes are.
We prefer to prototype things that we know are going to have less problems. Which is exactly why we don't build off-center mecanum drives.

I'm not saying it won't work to have an off-center mecanum. However, you will have you compensate for drift in code or with suspension, which takes time.
We wanted to go mecanum, but found that our play style would limit their effectiveness. I like mecanum. I'm just saying that putting the center of mass so far forward could invite problems.

I think you're missing Gregor's point completely. His point wasn't to say that your team made bad design decisions, not at all. His point is that you're giving firm, absolute-sounding advice to other posters without having any experience with the mechanism yourself.
When you say things so definitively and firmly like that, it implies a level of confidence in your knowledge that goes beyond you having read someone else say something like that somewhere else on Chief Delphi once. It's disingenuous, and it is VERY easy to post like that, give bad advice by mistake, and hurt teams who listen as a result. Trust me, I've been there, it's not fun.
His other point was that by deciding an idea has no merit (won't "actually work") without any prototyping, you're limiting your options based on preconception rather than evidence. His follow up post is indicating that perhaps
his own team has had experience with mecanum drive that makes him confident in his own design choice.
If you aren't precisely sure of what you're saying, don't say it like you are. One of these days someone just might listen.
