Can I mod my 710-15ikb with parts from a 720?

Please throw some suggestions; Im not asking only to be told “buy another laptop”

i.e. upgrading i5 to i7? I know the only options online ive found was a RAM upgrade and SSD upgrade, but I was however thinking along lines of the chip upgrade? Also how do I find the part for a new wifi adapter; as this models known for issues with disconnecting
