That does sound easy, but be forewarned (as you have already a few times)
you could be stepping down a long, steep slope. The thing most forgotten,
was the schematic side. If you're changing the footprints you'll need to
do that on the schematic too. Sounds like additional ways of incorporating
human-error, right?
My recommendation would be, leave the legacy as is, and if the ECO added
new parts that can from your lib., fine, use your lib. parts for that.
Making additional changes will only add time to the cycle, and chances for
error.
Good day.
