Not if you want desktop performance comparable to a Core i7/i9. The ARM64 A## chips can perform like desktop chips but they can't sustain that performance without thermal throttling. To offer sustained performance they'll need cooling (and probably also more cache, deeper pipelines, etc.).
ARM64 is not really that much more efficient than X64. It's slightly more efficient due to simpler instruction encoding but it's not huge. Instruction decoding is not the majority of the silicon on a modern chip.
