Re: Mount ideas for the vertically gifted
By RAW, no. Dragon Cohort only works on a specific list of dragons within the Draconomicon. This includes only metallic and chromatic dragons as well as a couple others (pseudodragon, wyvern, dragonnel, and spiked felldrake). I think its fair to expand the feat to include other choices, like half-dragon rhinos, but it requires DM approval.
