Tree nut challenge

My daughter is scheduled for a tree-nut challenge on Friday and I'm trying to figure out what combo of nuts to bring.

Back story - dd was diagnosed with a milk and egg allergy when she was ~1 year old, ped. allergist also looked at peanuts which she was also found to be allergic to peanuts - I think it was Class 5 at that point. So, we avoided all tree-nuts as well.

The most recent RAST put her at at Class 2 for peanuts and negligible to 0 for all nuts but she was negative for hazelnut, almonds, walnuts, cashews and pecans as well as a trace positive for pistachios (? allergist said that it was more likely a negative due to something, but I forgot what) with a more recent SPT. He is offering a tree-nut challenge now and wants to test her on hazelnuts, macadamias, pecans, walnuts, pistachios, almonds and cashews. He also said we could do individual nuts only if we wanted, but that would just mean it would take more trips up to his office (the office is almost 2 hours away - we live in rural New England).

Sooo, the question is - if we were to buy all of those nuts from the peanut-free source suggested by the allergist, it would cost over $140!! Plus, what if she reacts to the mixed nuts - we won't know which one she's allergic to so then we're back to square one. The same source also offers a mixed nut package which contains all except 2 of the nuts the allergist wants to test her on - the package is also peanut-free. Could we use this mixed nut package instead? I'm leaning towards yes because they are peanut-free, and if he is going to be mixing the nuts anyway if we do all (except 2) of them at once, there's no difference. Then again, if we test on only a couple of nuts, then there's a better chance of her getting a negative and being able to eat those particular nuts and nut-products if processed in a peanut-free or dedicated almond or hazelnut facility.

What would you do?

Forgot to mention that she does have eczema as well if this makes any difference.
