Your plan to use a 1.00mm thickness instead of the default 1.55mm increase the price by around 50% on, as example, WEdirekt. Why you need this thickness? Most time this is really useless and only increase the board costs. You should also think about bending, bga and small thickness.
I want to use a known 6 layer PCB stacking of materials / thickness that we know works with the Calypso/Iota/Rita. Particularly on the RF side, I don't want to spend time re-calculating all the impedance matched / controlled parts. That's the part that is hard to measure if we get it wrong. So just do the safe thing and stay with the "known working" case.
