Creator's Will is an SLA that lets you cast Minor Creation or Major Creation as an SLA. Whether you can use that to make an item made out of multiple different things is debatable, I suppose, but in the case that it can, this scheme would appear to be possible, yes.
Otherwise I don't know that an all-adamantine arrow-launcher, specifically, would be feasible, but something should be workable.
since the CR is based on damage output it could be shooting over sized ninja stars as easily as arrows i suppose which makes more sense then bolts I suppose.
as for he other comments I apologize for no being specific enough, creators will is part of the creation school, it allows you to use major creation and minor creation several times per day as a standard action.
