Yes we have been working on ridables and new items/graphics for a patch update in the future. There is on eta on this atm. It very time consuming and takes alot of effort. We have a nice collection of atrwork, but have run into some snags with old MUL files from the earlier patch and the new updated UOP file type in later versions past client 7.0.22 We have already done so much graphic work and additions to our patch, it will just take some time to implement. It's on the "list" to do:)
Kane was already poking around with this idea a couple weeks ago. But there are some issues. So maybe if he can find a work around. but it will more then likely be well in the future, he is a busy man, Ingame, more so in RL.
