Surround speakers slightly in front OK?

Merry Christmas! The family is still asleep, so I thought I would post a question while I'm waiting. I posted previously about my new home theater system and the responses were very helpful.

Because of my room setup, the easiest place for my surround speakers is to the side and just in front of my seating position. I know they are supposed to be directly to the side or just behind, but that poses considerable mounting problems. Does it make that much difference? Thanks.
