I frequent the Lounge forum which tends to have more electric players. There, over the last few years, this “neck shape - pain” topic has come up a coupla times. As I recall, some of the players with trouble preferred the “V”/“soft-V” shapes.
Having previously found the V comfortable, it should work out for you.
If you made modification and didn’t like it, you should be able to recover some of the value by selling it.
