I don't believe they created anything to replace the Epics. But by the sound of things I think you would definitely be interested in a Ludwig Centennial Zep config. Quality wise the Centennials are one step higher than the Epics, plus you can get your Bonham sizes. I don't believe you can get those sizes in any of the lower level Ludwig kits (Accent and Element).
As for the Epic line itself, the closest to Bonham you can get is the Pro Beat config. That comes with a 24x16 kick, 13x10 rack, and traditional 16x16 and 18x16 floors. I just checked on eBay and a couple places still have them in stock, plus you can find them used.
It will still give you a very thundery Bonhamesque sound, but if you want the exact replica with the 26x14 and 14x10 go with the Centennial Zep.
