[aur-general] How to replace in AUR a PKGBUILD providing split packages ?

Hi there. I maintain the package-base lib32-smbclient [1], which provides packages lib32-smbclient [2] and lib32-libwbclient [3]. I'd like to simply rename this package-base to "lib32-samba". Since these packages already exist in AUR, I cannot simply upload and replace them. How can provide the renamed package base, replacing the old lib32-smbclient package-base?
