That would probably work if everything is the same size and you are perfect with the naming convention.
I would probably just import the pics into AE, select the layer you want to replace in timeline, select new asset in project window and press “Cntl + Alt + /” to automatically replace it. I just like to see each one to make sure there isn’t some crazy issue that pops up with the replacements.
Another thing to consider is, if you rename new assets, replace old ones, you are effectively deleting assets, if you don’t have a copy, you will be banging your head against the wall when the client says “remember that picture we used that one time, let’s use it again.” —just my 2 cents.
