In the comments for that entry, Porky mentioned that he could help generate a d1000 table, and that we ought to do it as a crowd sourced project. I did not get back to him as quickly as I ought to have, and so he went ahead and started the table on his blog, with part one, head.
This is a most excellent table with 100 options for an inquisitor's head, ranging from scars to baldness to voxboxes and gills. You should definitely check it out, and I feel that it has pretty broad usage beyond Inquisitors. It also has some terrific imagery, which gives me some ideas for models as well, so the project is working! (e.g. a brain hatch held in place by a cord and with purity seals)
However, it is not exactly what I had in mind either, which is great, because we can pursue this thing concurrently, and either end up with one mega d2000 table, or blend it all together in to a lovely mess of a table.
What I had in mind is this. That an Inquisitor gets d4 rolls on the chart per level [i.e. a level 3 blunt gets 3d4 rolls on the chart], and that the first d10 rolled breaks the table into categories. Having the Retinue roll on the chart would be optional, but it seems that the Acolytes at least should roll once on it, merely as inquisitors in training.
Having equipment, random additional Psyker powers and stat changes as part of the table gives it some more old school flavor, as you would not know what you are going to end up with, which for me is part of the charm of these things. So stay tuned for more of this as it develops, and do check in on Porky's table, and contribute if you have any ideas.
