Building a claw post-ship

[somenerd]

My team's robot is coming together, and it looks like we could bag a working robot on ship day (if we wanted to). We will have a mechanism (an arm with a rather simplistic hook) completed, as well as a functioning 6 wheel skid drive.
We plan to keep the control system (cRIO, jaguars, sidecar, etc mounted on a plywood board) to give our programmers a bit more time to refine the code.
I was thinking about using the rest of our withholding allowance and the time between ship and our only competition (DC regional) to give some of the team a chance to develop a claw that they had been pushing for. We used a length of 80/20 for the arm, so attaching a possible claw onto the arm should not be too difficult (although I am an electrical person).
Good idea? Or terrible plan?
