An 80 kt reject on a 10,000 foot runway is not a big deal. I don't understand why you would want to take an obviously broken airplane flying......
Not saying it would be a big deal, Big Pistons, but (a)SOPs are there for a reason (b)take-off is not the time to be deciding if you or the manufacturer know better (c)an 'obviously broken' ASI is not a big deal to be taking into the air....especially when you can almost guarantee it's going to be a button push to solve the snag. Remember, we're not talking about a single-source pitot-static instrument here but a multi-source air data computer. The ASI problem is solved by selecting a different ADC, simple as that.
