Hi Phillip,
If there are multiple records of the same recipient with same email address to cover up the different data checks then yes, you can send the different variations to the same seed address by adding the same seed as many times as the no of variations you have for your email delivery .
You can test it by sending test emails to your id .
Also, seeds won't be deduped but the actual recipients would be by default delivery exclusion rule.
You can uncheck "Exclude duplicate" option in the delivery

Hope this helps.
Thanks
