"anyone has same ideas?" <-- I'm not sure what idea you're referring to in your post. What are you rethinking? What's different? If you don't want to use the touchscreen, then you don't use it. If you want to take off the touch capability, just pull the touch glass out. Why would you replace it with a cheaper screen? Quality will only get worse with a cheaper screen. Since your setup is done, why rip it apart? I don't understand what it is that you're "re-thinking".
