Oh man... if you put springs on stock struts... They're gonna blow out the first day!!!!
Nah...j/k
If you don't mind doing twice the work then by all means go ahead. They'll be fine on the stock struts and you shouldn't blow them at all. Personally I think it'd be a good idea to try the springs out on the stock struts for awhile. So that way when you put the new struts in you'll be able to feel the difference. Also you can gauge any potential problems beforehand. Just my opinion.
