I tried to understand as much as possible about whether this would work, and what I found was:
PQM: Since this is a United issued ticket, there should be no issue picking up 1700 mies here.
PQD: It looks like I'll also accumulate PQD, based on the fare price but not taxes, etc. This was a little ambiguous. The Lufthansa fare was around $600 in fare in $600 in taxes, but somehow the UA fare broke down differently.
I went ahead and purchased the UA fare. Here is how the itinerary ticketed and priced, in the end:
