You're playing with fire for a couple reasons -
The struts/shocks are valved and tuned to match the spring rates for springs equipped on the 2.5. If you use 3.5 springs, they have different spring rates.
Your problems at first look are relegated to the look. You will eventually blow out your shocks and struts in addition to shredding tires and working over suspension components like bushings, tie rods, etc over time.
What I have outlined above is the case if you have four matching sets of springs. You do not, which compounds all of those issues. It also makes for really bad vehicle response with the front and rear being so out of whack, say for example in the situation of making emergency maneuvers.
