Dual-architecture CPU?

With new speculations about Apple switching its Macs to in-house designed ARM processors, would it be possible for their processors to natively support both ARM and x86? How much performance and die space would it cost, how much complexity and power consumption would it add?

This is ignoring the legal and licensing aspects and assuming that everything should be shared except for the instruction decoders; sticking a complete ARM core next to a complete x86 core is not what I'm wondering about. Being Apple, they could limit themselves to only 64bit.

Apologies if this question has already been discussed, my limited Google-fu didn't show anything related.
