about buying plan

My current purchase plan is Fuegan, Firedragon, and Falcon I'm debating whether to buy Baharoth, Swooping hawk, and Rakis on top of that, or just Swooping Hawk and the new War Walker box. Due to financial limitations, I have to choose one or the other this time, which is better? I don't mind if it's a combination that costs £115 or less, the units I have now are

3 Ynnari epic heroes

1 Autarch wayleaper

An old combatpatrol box(including guardian, wraithlord...etc)

12 Troupe including master

1 Spiritseer

5 each Wraithblade and Wraithguard

1 Support Weapon

1 Eldread

10 Striking scorpion

I'm holding off on buying another Spiritseer for the upcoming Combat Patrol. Can you recommend a shopping list for £115 or less?
