I believe that is fine. However you need to remember that your bumpers must be within the 2-10in zone and must be supported by you Frame Perimeter. The bumpers can not have a zone bigger than 8in, in which they are not supported by the frame perimeter. Someone else may wont to explain this, as i am a bad explainer.

here is the rule i was talking about
[R33]
Bumpers must be supported by the structure/frame of the Robot (i.e. each end of the Bumper must be rigidly attached to the Frame Perimeter, the gap between the backing material and the frame must not be greater than ¼ in. and no section of Bumper greater than 8 in. may be unsupported). See Figure 4‑7.
