I'd say that icon maker isn't necessarily needed. We would be able to use allready created icons, and if the project is finished, more icon artists might be interested in creating some icons.
Triggerer, what would you need? Because I might be able to help at that one if it isn't too advanced.
By loading screen maker do you mean like one that has to create a painting/drawing/something-like-that? Because again, I wouldn't say a loading screen would be that much of a necessity.
