For those focusing on bulk/larger grip I'm a big fan of the Deda Trentacinque. That said, the Deda RHM shape need to work for you to go that route, and you need a new stem too which only comes in 8 degrees. If those both work for you solid option.
I realized he OP asked about gravel/CX bars; Dedas don't build these with any flare.
And you still have the fun of choosing tapes!
