21 Fret to 20 Fret P/J Neck?

[thebrig]

Can a 21 fret P/J neck be converted to a 20 fret P/J neck?

I'm assuming that the heel dimensions are the same as a standard neck, but the the extra fret just overhangs the body.

So my question is:

Can the extra fret be trimmed off and rounded to match the heel so that it then becomes a standard 20 fret neck?

Hope I'm explaining myself ok 🤔
