It's been done but you can only cut it in half and it takes a while to heal. https://www.reef2reef.com/threads/gig-‘ems-grand-gigantea-gathering.850187/page-4#post-10305262

Yes, it's been done, but success was never proven. I definitely trust the person who did it, but I don't recommend that others try it. Since Stichodactyla don't reproduce way, we can't expect a high rate of success.
