on second thought you can always use option of 4 wives.
its not very practical in this day & age unfortunately
i can get a second wife from a poor background but i know that my first wife will leave me if i do that even if doesnt want to her family will make her] as polygamy is thoughtof as the ultimate insult to women these days
i have thought of all options including legality of concubines /mutah but these things are not clearcut according to our times and there is a great danger of falling into sin /commiting fornication
