Anyone know if this is possible?

Hey guys I was thinking about something and was wondering how difficult it would be. I love '68 R/T coronet tail panels in my opinion its got the baddest ass of em all lol. My favorite of all the coronets though is the '70 model because of the grill. I think the the 68 tail panel would look fantastic on a 70. Reason being is the shape of the tail lights would compliment the grill very well Seeing as how they are almost the same shape. What do you guys think would have to be done to put the 68 tail panel on a 70?
Or rather put a 70 front clip on a 68?
