LS does not distinguish between a token based relevance equation and a question based.
Therefore - if your idea was possible - LS cannot decide if a question has to be hidden because of the token or because of the answer to a question (Like: This question only if Q2=="Yes")
If you really like to give each one his customized questionnaire, start working.
Well prepared, it shouldn't be to much work.
1. Write your questionnaire once in a word processing program and create defined text blocks (autotext).
To customize your questionnaires you only click and insert the desired blocks.

2. Do it in EXCEL or OpenOffice with your questions on seperate sheets
On a "command"-sheet you have all questionnaire designs, like
1,3,5,6,7,15,22 (This respondent gets questions 1,3,5,6,7,...)
2,4,11,12,13,17,18,...(This respondent gets questions 2,4,11,...)
A macro now collects the questions and writes the result to the "result" sheets.
3. The more sophisticated solution with a php script and the library
