Broken LCD and bent body

I got into a bike accident where my phone flew off the mount. The lcd cracked and the phone was bent slightly at the bottom of the phone.

I brought it to a shop for repair and they told me it’s undoable because of the bent as whatever screen I replaced, the tendency of it cracking again will be there unless I am able to ‘straighten’ my phone.

I see some sites selling the entire mid frame and housing of the phone, albeit OEM. Is it at all possible to migrate all existing parts over to the new frame and body and still use the phone as it is? Because as of now that cracked iPhone 12 PM is essentially an expensive paperweight
