[mesa-users] White Dwarf Mass Gain

I would start by accreting C and O on a pure C/O white dwarf. This to
avoid any complications at the surface. Even then you will probably get
trouble evolving the growing convective core as the C burning luminosity
increases. But I have not yet tried it myself with Mesa... so
good luck !
