Since you are able to start with 4 Source Hunters now, if there won't be a flash gui break through, you could use a script and trigger/dialogue heavy option similar to how most older mods for Fallout 3 and Fallout New Vegas used terminals.
Also you might try to contact someone from the SkyUI team from the Skyrim nexus, all done in flash.
For appearance try to copy the mirror to the start point.
For the skills etc. you will need a custom solution.
Yes, my flash skills are no where near the level to successfully recreate what is needed within a short time-span. Not trying to false hope people, which is why I have been honest with my limitations, or if someone is good in that technical area, they maybe interested in getting involved.
I was thinking of other options, but I wouldn't be able to do name or class. I could put the respec demon's option there, so you would get skill point reassignment (no spells, perhaps spell books?) and the mirror for appearance.
I read somewhere that the Larian developers went on Holiday so there will be a lull in any updates or replies.
