Jakob Ryan or maybe a future second
I think that is too much.
I think we have shown over the years with Roughie, Howe, Frampton, Clement, Dunn that you can pick up quality defenders (elite in the case of Howe and Clement) for cheap. Maybe Charlie Dean is another one of those.
I would be more inclined to use a second round draft pick to help bring in a tall forward or midfielder.
