Hello, Yuvi,
Activating another theme for a while should not break anything (only widgets may change positions, so open Appearance > Widgets in a new tab) if you are worried you can:
1/ Create a test site, a full copy of the existing one, and do the test there;
2/ Believe us that your question is independent of the theme, and contact support of WooCommerce.
Kind Regards,
8theme team
