Wyrmwood Hex Tile Planning

My goals: 

• Have one of each configuration and color
• With four tiles (minus Tavern) and eight woods, I want a pair of each tile
• Each tile pair should be different woods
• Each tile pair should also be on opposite ends of (1) color and (2) price
• And based on all of this, it should be easy to distinguish similar-looking woods (e.g. if it's a very dark Solo Tile, it has to be Ebony because my pair of Solo Tiles is either Elm or Ebony)
• For each hex tile pairing, there should be one more of the cheaper wood tile than the higher-priced wood tile (e.g. 2 elm & 1 ebony, or 3 padauk & 2 wenge)
• Total number of hex tiles should be 14 because that's two hex tile racks or one hex party tray's worth

What I have / am aiming for so far:

• 2 Solo Tile / Elm
• 1 Solo Tile / Ebony (own x1)

• 2 Duo Tile / Cherry (own x1)
• 1 Duo Tile / Bolivian Rosewood (own x1)

• 3 Card Tile / Padauk (own x1)
• 2 Card Tile / Wenge (own x)

• 2 Combo Tile / Black Walnut (own x1)
• 1 Combo Tile / Purpleheart (own x1)
