Nutzz, as of 2:30 AM EST on 4/27 I found the following routing roundtrip. I'm sure there are better routings, but it meets most of your criteria. BTW, I'm relocating to PHX, as well, from BOS in June, so the topic interested me.

5/24
NW 256 PHX-DTW (V), NW 426 DTW-MCO (V), NW 825 MCO-IND (K)
Sub-Total ~ 3,455 EQMs

5/30
NW 1008 IND-DTW (Q), NW 757 DTW-MSP (Q), NW 107 MSP-PHX (Q)
Sub-Total ~ 2,402 EQMs

Grand total ~ 5,857 EQMs, 6 segments, $437.29 all-in. I got the itinerary to come up on NWA.com by searching one day before/after 5/24 and 5/29. Good luck!
