Digestive expansion and ogre stomach are pretty much the same thing - I wouldn't let them stack.
You know, on a tangent, one thing that always bugged me, from a logic standpoint, was how certain mods can lower your lifestyle costs, but the sustenance power, which cuts your food needs by two thirds, has no affect whatsoever on lifestyle costs.
I think that has been addressed before. I think one houserule I read was that Sustenance gives a 5 or 10% discount, which is still probably less that what it should be. Likewise, the Digester Endosont (Augmentation, page 71) reduces food consumption by 50%.
And don't forget Photometabolism! That's another 10% off of Lifestyle costs. Sure, it's not as good as Ogre Stomach, but it's awesome.
