But that is not allowed in Germany. Unbalanced loads are only permitted here up to 20 A. In Austria and Switzerland the limit is even 16 A.
As I look in specification of wallbox from Ford, you have time for full load around 3.5-4 hours. Even if the Wallbox is of 7.4 KW and from calculation you should have 2 hours of charge (14.4/7.4=2 hours) actually the charging speed is only at 3.7 KW (14.4/3.7=3.5-4 hours). Same if you have 22 KW wall box. The maximum amperage for charging for kuga is 16A and only one phase.
So check here to some company that install and comisioning the wallbox
