Well, if there's Skywalker in OT and Skywalker in PT then you'd need to change the names, too...
Why?
If an editor can figure out a number of dances around it being obvious that Anakin is Vader in the PT why would it be an issue?
Sure they both have the same surname, this has been true since ROTJ (and I'm not that keen on much of ROTJ either in it's current form).
It's a large galaxy.
I hope it will surprise you (as it did me when I worked in an insurance company) the large number of people in Britain with the surname Cobbledick.
Presumably many of them have distant relatives in 'the colonies' too.
Not many of them will be father and son.
The PT has many compounded narrative screw ups but that isn't one of them.
Having Anakin live on Tatooine as boy is a bigger one, made worse by having Owen actually know Anakin let alone genuinely be connected to him.
Of all the places for Obi-Wan to hide Luke, he picks a farm Anakin knows about and has visited on one of the most traumatic days of his life, on the planet he grew up on, owned by his step brother.
This is what makes Luke's name a problem not the name itself.
The only way you could keep all that and make sense of it all is if Obi-Wan is setting a trap for Vader with little baby Luke as the bait (we know Obi-Wan is a lair but that really makes him out to be as morally compromised as Vader...from a certain point of view).
If Anakin grew up on another planet and never met or was even related to Owen, Luke being called Skywalker isn't a problem at all.
Lucas was too obsessed with providing fan-service (or obvious brand recognition) to concern himself with those details.
