It can change priority rarely yes. That is unlikely, but it might happen if you use many different components. But when two different placements result in the same list of possible perks, with same ranks and priorities, I think different placements are just superstition.
Additionally, I think when a perk can be obtained with less materials the chance remains the same with more. If you get 4-5 using 4 or 5 components, then using 5 does not further increase your chances.
