I don't see much of a problem with doing a couple 8's on Deadlifts on Wednesday as long as they're kept light Hops. Since they're not a priority and you've put them on Wednesday, I'm assuming you'll be using a relatively light weight and won't be pushing for any records on them?

If you are planning on pushing for records on them, then they could become rather stressful like Eric said. I'd also suggest moving them to Friday in that case.

Glad to hear your first session went well.
