If one wants to come up with something unbalanced against the Petroff, what are the pluses and minuses of playing 3. d3, and going for a KIA setup? Are there any good resources out there on this approach?

Just bumping this in case anyone has any insights. Nobody has any experience on either side of this?
Compare with this:
Black goes for a similar position down a tempo (playing e6 and then e5) and with the Bishop placed on e7 rather than c5.
Perhaps you might consider a reversed Philidor instead.

Ah, thanks. That does help explain why it's not often seen.
A revsersed Philidor could be interesting -- I'll give it a look.
Evans (1975) The Chess Opening for You discusses both 1.e4 e5 2.Nf3 Nc6 3.g3 and 1.e4 e5 2.Nf3 Nf6 3.d3 on pages 86-88. In his treatment they can transpose into each other: 1.e4 e5 2.Nf3 Nc6 3.g3 Nf6 4.d3 d5 5.Nbd2 or 1.e4 e5 2.Nf3 Nf6 3.d3 Nc6 4.g3 d5 5.Nbd2.
However, I agree with blank0923. In a Philidor it's not considered great for white to play d4xe5 because after ...d6xe5 black's bishop is free. In a Pirc (e.g. in the Classical Pirc) it's thematic for white to play d4xe5 because the black bishop is misplaced on g7, in fact then a main idea for black is ...Rf8-e8 and ...Bg7-f8.
Another line to compare with is 1.e4 e6 2.d3 d5 3.Nd2 Nf6 4.Ngf3 Nc6 when white should probably avoid 5.g3 dxe4 6.dxe4 e5 with ...Bf8-c5, ...a7-a5, etc. They usually play something like 5.c3 a5 6.Be2.
In the specific lines Evans covers, I think white should vary with 1.e4 e5 2.Nf3 Nc6 3.g3 Nf6 4.Nc3 (Glek Four Knights) or 1.e4 e5 2.Nf3 Nf6 3.d3 Nc6 4.c3 (a Ponziani sideline) 4...d5 5.Nbd2 a5 6.Be2 (Reversed Philidor) or 6.a4 or even 6.h3!? (Lion). These are not great options for white but at least black does not get an initiative.
