Changing passphrase parameters (s2k options)

I've been reading about symmetric encryption of the private key.

When I tried to experiment with the `--s2k` options, attempting to
change the passphrase on my key, I found that they were ignored. A brief
search identified issue 1800 [1] on the bug tracker which was last
updated in 2015, some 20 months ago.

Is it possible with gpg2.x to re-encrypt a private key with new s2k
options ?

I have gpg (GnuPG) 2.1.17 libgcrypt 1.7.5.
