Is Incoming Trust with Domain-Wide auth & Outgoing Trust with Selective auth possible?

Hi,

We have 2 Forests(A & B) at Server 2008 R2 Forest Functional Level.  Currently have a 1-Way Forest Incoming Trust to A (in other words B is 'Trusting' A) with Domain-Wide authentication and now have requirements for an Outgoing Trust to B from A (A is 'Trusting' B) with Selective authentication.  In my lab I cannot implement one side of the Trust with Domain-Wide auth and the other side with Selective auth?  Is this possible with a Forest or External Trust?

Thanks for your help! SdeDot
