The first problem I can see with this is that it will be a big thing. As in, a full book just for this one character generation system, as each choice is going to need to lead to a different set of questions (with some overlap) so that it's harder to game the system by just picking the best options for each question, as the branching choices mean that by picking one option others close to you.
Thoughts?
It's an interesting concept and attractive conceptually (I like the idea of handing this thing to a player, too, but I foresee a few problems:
1)
Anyone who seriously wants to game the system is going to go through the book backwards and forwards to find out the best possible result.The counter-move to this is to hide the mechanics, but at that point, you might as well be simply getting the players to describe the PC they want and making them for them (and you don't need the system you propose to do that - I've done it before for SR players, particularly newbies), and that will be really really off-putting for a lot of players.
So anyway, assuming you are transparent about it (like all the other chargen systems mentioned, which are 100% transparent), people will still game the system. You will likely prevent some particularly obnoxious combinations, but you will probably totally allow others (unintentionally - no-one is perfect! I know I'm not! And it would take a huge amount of play-testing to track down all the potential issues - and some people wouldn't even see them as issues).
2)
At certain points, you will just have to break down and use some kind of standard chargen rules, because it's too fiddly to go with a questionnaire.Gear in general, particularly cyberware, would be one area, unless you are willing to come up with dozens of "gear packages" and "cyber packages" (which will no doubt bring their own woes, as some will be equal in nuyen cost but clearly far more or less optimal than others). Spells would be another area, because there are just too many to account for. Adept powers likewise. Knowledge skills, too, as they're meant to be completely personalized. Even normal skills will be difficult to account for.
3)
Accounting for new material will be difficult.Eventually new magical traditions, new approaches to power and so on are likely to appear, as well as new spells, cyberware, gear and adept powers, some of which may just not fit into the questionnaire you've created. You may have to re-work significant parts of it to account for them, which seems like it would be a great deal of work for something that you would only ever use at the beginning of a campaign or occasionally when a 'runner gets gacked.
The main upside would be for new players who don't really understand SR's rather complex chargen rules (it's particularly difficult for them to understand the value of certain choices without having actually played quite a bit), and it could also introduce them to aspects of the Shadowrun world which might be a bit weird and make sure that they don't miss out on things like Commlinks and Fake SINs.
Like you say, though, it'd be a huge amount of work, especially ensuring the results ended up reasonably balanced. I personally couldn't see it being worthwhile unless you were constantly introducing new players to SR (like, on a monthly basis), because if you just want to avoid people taking options you feel are obnoxious, you have two far more simple options:
A) Get them to describe the character to you and then build it yourself, not allowing them to use the rulebooks to make decisions - this requires fairly extreme trust between ref and player and also will make characters less fun for a significant percentage of players, because they enjoy chargen and/or characters who are perfectly customized - but your proposed system also has these problems AND means a lot more work for the ref.
B) Just ban stuff you don't like. What people find "too much" varies from group to group, which is partly why SR has so many different chargen systems.
Finally, I'd just say, you'd also be much better off making this a website rather than a physical book, if you have the skills or know someone who does (questionnaires which produce complex results like this are not trivial but they are not likely to be weeks of work, either - esp. if you work it out fully in theory before "webifying" it).
