First of all I respect you guys in your decision if you simply wished to redirect the funds elsewhere and wanted to leave it at that. With that said, the wish for a character viewer is still out there. With beyond double the success of that original 80k goal, would it still not be possible to hire someone else to continue a character viewer? Especially considering the new continuous stream of funds from Patreon.
The first thing to say is that the bottomless pot of money isn't that bottomless. Fen can correct me on this, but last it was discussed about half of the apparent monthly total doesn't even clear. Of the remainder, Fen employs Savin and Gedan full time, Shou I believe part time. So whilst TiTS is solvent there really isn't a vast sum knocking around for ambitious projects, despite what a glance at the Patreon suggests.
What a character viewer would require is a talented, trustworthy, extremely dedicated and hard-working artist who had a basic grasp of code, understood the moddability required and be willing to be picked up again after the event to continuously supplement his/her end product.
This individual does not exist, or if they do, the rates they would charge puts them out of TiTS' reach. Misty above has exaggerated the level of complexity a bit - things like height and clothes could be left to one side for the sake of streamlining - but really, it's a Sisyphean task once you look into it.
In the CoC years bushy-tailed volunteers would often turn up, offering to improve the character viewer or build another one from the ground up. Inevitably what would happen is that they would turn one or two models out and then quietly disappear. What I guarantee would happen if an enthusiastic artist offered to do one for TiTS, or one was contracted, is this: they would create a basic system, get a few different bits and pieces working with it, maybe get as far as creating a Leithan lower body... and then there would be nothing but radio silence. We'd be left with a knot-coded abortion which will torment everyone with its wasted potential, which means that a great deal of effort and possibly money will have been spent on getting something worse than nothing.
As already said: It's not impossible, but close enough to it that it's not worth considering.
