I think JLAA has proved he has the potential, even if he is going through a bad patch. He also has some pace, which is an asset especially at this level. I don't think Cole has that much potential to be honest and I doubt he will go that far.
In terms of centre midfield I recall you were disappointed in lack of praise the current incumbents after arecent game - so presumably some quality there. In terms of whether there is a plethora and whether I think the current two can manage on their own the answer is no and no. I also think that whoever you put upfront with JLAA out of who is left, you will always get what you always got - a sterile looking attack and we will just drift out of the reckoning.
Given lack of resource I would prefer to have the better quality footballers on the park with a third man in the middle and supporting JLAA might work - bring on Robbo or Zoum.
