To at least be able to fuse stabily you need to be in good nature with the other party (so like friend, sister, etc). Even though fusing with someone you hate or someone you are incompatible with due to personality (like how amethyst is wild, sapphire is cold, and Ruby is headstrong so Sugilite is unstable) would make the fusion much more powerful (like how malachite is as tall as Sugilite, maybe taller, and she is composed of two gems while opal, who is composed of two gems is like 15 feet tall), it is still risky.
