Nah, it was pragmatic. She was losing crew that couldn’t really be replaced. And she was on the verge of losing a very important crew member, Tuvok.
She wasn’t about to let that happen.

If Tuvix retained Tuvoks skills, keeping Tuvix would mean not having to deal with Neelix, however. Im sure she considered that as a reason to keep Tuvix, before her bloodlust won out.

Nah, there was the clear risk that Tuvix exhibited the worst traits of Tuvok and Neelix. That would be a total nightmare. Restoring the original was the proper choice. At some point an opportunity to get rid of Neelix could appear, and you could retain the original Tuvok without loss.
