A Writerly Question

I'm asking for opinions here, people.

One of my current works-in-progress is what I'm calling "Southern girl returns to the farm." This was originally a play for an undergrad class, but I'm interested in turning it into a manuscript. As it stands now, it would be a novella length (which is fine and good) but I want it to be full-length novel.

My question is: would it be too jarring to have various POVs, like William Faulkner's As I Lay Dying or Lee Smith's Oral History?

I'd like to keep things third person, and I'd like to have the POVs come from the main character (D), a farm hand (B), and D's younger sister's friend (M). Would it be wierd for the reader to see things through the eyes of characters unrelated to the main character?

[Now that I ask, I realize that particularly in Faulkner's The Sound and the Fury, Caddy Compson is the "main" character, but we the reader never hear directly from her, only the men in her life; same goes for Lee Smith's Oral History's Dory. I guess it's a stupid question because technically, a writer can write whatever they choose. The questions should be will the work land an agent or sell to the public, and that's all about the voice/tone/plot/etc.]

But I'd still like some opinions..... :p
