a GDC answer to a question regarding a similar situation:

The prohibition in Rule <R19-B>, as amended in Team Update 2, is against BALL incursion inside any particular MECHANISM on the ROBOT. It is understood that the BALL may enter inside the vertical project of the FRAME PERIMETER of the ROBOT (i.e. be "inside" the ROBOT boundaries). A situation where the BALL traverses "inside" the robot boundaries (e.g. as it falls from the BALL RETURN and bounces off the top of the ROBOT), but does not enter a MECHANISM by more than the permitted 3 inches, would not be PENALIZED

my interpretation of this combined with updates #2 and #9 is that unless the "V" shape is designed to manipulate the ball, then it is legal.
in my opinion, unless you have a complete "cage" around every part of your robot to block the ball, a ball will enter the frame perimeter more than 3".
