I see no reason why you couldn’t as long as you’re able to get a solid and safe connection to each prong. My S19 power cords were connected via wire nuts to 8ga wire in a junction box. You’re basically doing the same thing but with a plug and outlet.
Run all my asic that way I have that same pdu per what ever you want to call it made myself 4 others that way bought one made 4 myself not a problem in 6 months
