audiofreak32, How do you have your 4-10s positioned next to your DIs since I will be doing the similar placement?

Basically they are just to the outside of the DI's, maybe 3-4" apart, faces are aligned.  I sent a scaled drawing of my room to Eric before I bought them to show what I was intending to do.... he replied "That is exactly what we intended for people to do for placement".
I will take a few pics and get uploaded shortly.

Do you think I can get similar results with the 4-10s to the inside of my DIs?

You should experiment with placement. I place mine on the inside of the Pendragons. I had them on the outside, but found that the soundstage collapsed a bit when they were on the outside. 
Hope this helps...
