It's not, apparently, a hard size of kit to accommodate in plenty of bags: as for stealth purposes, I'd suggest that you look at your own style of dress and where you go. If I were to carry a 'sporty'-looking bag, for instance, it'd stand out like a sore thumb on me, as would, very likely, most of the time, something 'executive-looking' like these newer Lowepro... what's-their faces, ...they look like a pretty common thing urbanite office-workers might carry stuff in. I'm blanking on the name of the line. Black ones with kind of a glossier stripe on them. Classy, but not *too* classy. (They actually look like great bags, too: it'd be nice for me if they made some look more like 'what artsy chicks carry.'
)
The big thing that'll make a camera bag stand out is if it doesn't *fit* on you in one way or another: A lot of where tourists and hobbyists go wrong is actually that their bag doesn't look like it belongs on *them.* Or in the place.
A 'basic black pro bag' might stand out if everyone's wearing backpacks with colorful trim, and one of those bags in turn may stand out if you don't look like you've ever owned athletic shoes in your life, and *very* often, in any case, photo bags look too pristine for how someone's otherwise attired.
People looking for ripoff targets or to lift something will also tend to assume "new bag=new camera." People who don't seem used to carrying what they're carrying will probably seem more-easily separated from them. (I like to try and 'break things in' appropriately asap. Get to know your bag by using as pillow. Unless you normally wear brand-new things.
)
So, try not to treat the bag as a 'separate object'....consider it a place on your person to put cameras. Choose something that may 'fit' on you. If it really looks like it belongs there, it actually will be the least-likely thing to draw unwanted attention.
Also, try to have it be physically-comfortable on you. Thieves read body-language. If you're not comfortable with the bag or treating it as too precious, someone may pick up on that. If you carry all the time, you'll blend in a lot better. Mostly they won't stop and examine every object they see: they'll sort of scan for what looks out of place, then size things up. So the more comfortable you are, (not careless, comfortable) the more likely it is they'll never even ping you in the first place.
