It's been a while since I last ripped from Radiant dawn so I might not remember all the steps correctñy, but here we go:
First, open a path of radiance iso with a program called GCTool (I'm not sure if wiiscrubber works there as well) and find where the battle models are stored. Then extract every single file that you will find in a character folder (every character works).
Now open a radiant dawn iso with wiiscrubber, find where the battle character models are stored and then find a folder called SwoLE, which contains edward's myrmidon files. Replace everything except the pack.cmp (which is edward's model) with path of radiance's files. That will make the character go to the famous T-pose in battle.
Then find the folder that contains the character you want to rip (for example, trueblade mia is SwoSW I think) and extract the pack.cmp and the tpl files, which are the textures.
replace edward's pack.cmp file with your character of choice and convert the texture files using a program called tpl converter. Then you should have the texture images in an usable format.
Close wiiscrubber (it automatically saves the changes) and run the dolphin emulator with 3d ripper dx. Start a new game and skip everything until you can control edward. attack the bandit and voila! you get the character of your choice t-posed. Get the frame with 3d ripper DX and find the character in a 3d editing program (know you'll have to deal with the weird double sided faces).
And that's it, you need a bunch of programs but in the end it's worth it.

I took a short break from Lucina because I want to request Zelgius and Greil for brawl. Right now I'm revising Greil's model to make it look better and making it fit Ike's bones. I got rid of the old face and made a new one, but still needs some work. I also modelled Urvan:
