Can you replace headlights without taking of headlight bucket?

im working on my 280z project car and tackling lighting currently. I went to remove and check the wiring for the headlights and one of the previous owners in the 80s decided to WELD the buckets to the fender... He did alot of body work to make the car have very minimal body panel lines and used bondo to smooth everything out. i thought that was just it until i took it off and its stich wedled... poorly at that. ill get them off but not right now.

Can i replace without removing the bucket?
