I agree with A_n_t in that if you're wanting to appear all thumbs the second shuffle does conflict with the idea.
The solution you mentioned - a sloppy riffle or overhand shuffle - would work, BUT, I think it would be better to have no shuffle at all (by you) after the initial mixing. You mentioned that you allow the spectator to mix the tabled cards - in my opinion it would be more deceptive to then take those cards and do the ace production, rather than mixing them further MYSELF first. With the latter the thinking spectator would assume the mixing by you was simply for controling the aces for the finale. With the former there is no solution, THEY mixed the cards then you instantly produced the aces.
Ive never understood when magicians have a spectator shuffle the cards only to take them back and shuffle them themselves, especially when its not necessary for the effect. It totaly defeats the purpose of the spectator shuffle. To the spectator the cards ARE well mixed, why wouldnt they be, they have just shuffled them. Why then would we question their shuffle to the extent that we shuffle them ourselves just to make sure ? The more logical thinking of your spectators will see this shuffle as part of the method, to them there is no other reason why you would need to shuffle an already shuffled deck.
Of course its just my opinion
