while i know close to nothing about raid, here is what i think:

1. you have no backup ( otherwise you could pull it off )
2. you are trying to achieve your goal through a tricky method ( me
thinks anyways :-)

is the loss of your data worth less than the cost of an extra hd? if
so, buy another hd. if not, make a clean install?

and assuming a 3 hd raid setup, would it not be wise to have a spare hd anyway?

what's the point?
