Can I dynamically re-direct to one of several URLs On form submission?

Yes - you can.
here's a scenario:
Say someone completes an expression of interest (EOI) form which asks a number of Yes / No questions and based on their answers, the form calculates a score in a hidden field.  You can then use the score to determine whether to redirect them to a full application form or a webpage explaining why they are not eligible to proceed further.

in a nutshell, all you have to do is:
1- Create a the form with all its questions using radio button elements. 
2- Add advanced values to every radio button.
yes =1
no =0


3- Add a calculated field that sums up all of your radio buttons.


4- Create a form condition, where you can easily redirect the form based on your rules. 
5- Configure the condition according to your needs, for example:
if Calculated is larger than x then set the result : redirect to URL 1
If Calculated equals or smaller than x - set the result : redirect to URL 2
