I just noticed you want to carry Nifty and an 18-55, which is an EF-S lens not designed to work on your 1D2. You sure about that?
If you check the F2 specs, the inside dimensions are 11x6.5x8.5" The 720-230 insert is 11x2.5x7.75". I generally swear by the 720-230 insert and I can assure you that your options with a gripped body like the 1D2 are to use only 2 of the compartments, or to stash the body/lens combo vertically in the bag. And that isn't going to work with the 70-200 if you want to close the bag. The shortest 70-200 is about 7.6", and the body will add a good 2" to the height of the combo. And the 1D2 is 6.1" high - it'll fit in the F2, on its side, but you won't have any space to spare for the insert to be usable.
If you want to stack the 50 and the 18-55 (or whatever you replace that with) in one compartment you could use a second compartment for the flash and collapse the third to accommodate the grip/battery housing. But you just won't be able to fit a 1D2 with 70-200, as you've diagrammed, and still use all 3 compartments of a Domke insert in an F2. Put an ungripped body like a 5D or 50D, yes. But not a gripped one.
Here's my F2 with IIRC a 20D and D60, 100-400 (about the same size as the 70-200) on the 20D, 24-70 on the D60, and Sigma 15-30 and Tamron 90 mm macro in the main compartment (720-230 insert). If there were a grip on the D60, you'd be able to close the bag over it, but as you can see there's no room for a grip if you want to use that end compartment.

You can see from this photo of the F1x that there's room for a gripped body to clear the 720-230 insert if you have that bag (or the F7 Double AF).
