it would for sure rub away easier. its been done by many-a-people. it's just the lazy mans way out of doing work.
also, OP: using spring blockers will work for now, but you really are not addressing the problem. you need to roll your fenders. it will five you an extra 15mm or so of clearance, which should clear the tire when the suspension compresses (by nature, a suspension gains negative camber the more it is compressed. therefore, if you can clear it while it is compressing then youre fine). if you leave it like it is now you will continually cut your tires until you need new ones. tires and cheap and you shouldnt be cheap in your solution to the actual problem. roll your fenders and im 97% sure your problem will be completely alleviated. you also can try running a small amount of camber, but anything over -2* or so will look stupid (this is another way of avoiding the actual problem).
