I don't think anything really "likes" to be an ELB there are just a few woods (yew, osage, etc.) that tolerate the narrow profile of an ELB. My advice would be to build a flatter bellied design with the oak. The ELB design just doesn't play to oak's strengths very well. I'm sure you could make one out of oak but it will take more set than if you had a wider flatter belly.
