@drill great question! I certainly looked into it extensively. Unfortunately it would've required at least a week with no guarantees for even seeing a Dibatag. It was maybe 4 times more expensive than the 2 weeks I was already spending in Ethiopia. At best I would've added maybe 3 lifer species- desert warthog, silver dik-dik and the dibatag. These certainly would've been special but hard to justify the price. So I decided to add Zambia instead- which ended up being a great destination for lifer antelope species anyways!
