Sounds like a fine plan to me, though it would have to be the sort of GenMods that are usually used as "test fodder".  Even then, there is no doubt that Steinman would have noticed irregularities in the number of GenMods being used for testing and the ones actually counted up at the end of each day, so he would know that they are gradually going missing.  Hell, he might even know of the secret entrance that Soames is using, if not that it is Soames that is doing the smuggling.  Steinman has his own agenda, and this seems like the sort of thing he would let continue under his watch so long as it wasn't interrupting his more delicate experiments.<br/><br/>As for the "Way Scary" creatures at the bottom, I doubt those will come into play just yet.  The worse of them are literally miles beneath the surface, so I can't think of any reason why the rebels or other GenMods would be insane enough to delve down that far.
