Oh, no question that I'm going to go with it like it is. Any "key change" (if there actually is one) might be accidental, but the chords are exactly like I want them to be. The issue is "resolution", though. If I'm going to ask for a melodic lead, key matters (or certainly MAY matter). That short melody also needs to resolve and/or modulate.

The real issue is "communication" though. I've got no choice but to let him/her do their own thing, but I feel like I have some choice in how I "hear" it as everyone hears music differently, and if I can't communicate that, then I've frittered away my input.

Side note: I looked up the chord formed by all the notes of both the D and G triads. Turns out it's a Gmaj9 and no naturally occurring D based chord was listed. Might be kinda fun to ask for something of an arpeggiated Gmaj9 (or some inversion thereof) to be considered, at least in part.
