FL. 2001 XJ

hey every one! Just wondering if any one could help me out on building a cheep lift to fit a 32 inch tire. I have had my 2001 jeep cherokee clasic for about a year. the control arms bushings are worn out and are making noise. I do not want to buy the factory crapy stapped steel control arms but, I am running on a cheap budget. I was looking at a tough country 3.5 lift on line. If I would install a 3.5 lift and then add the 2in blocks above the front springs and add the rear block to the existing add leafs would this work or be a bad idea?
