TPS43061: Top FET Reversal

Part Number: TPS43061
Other Parts Discussed in Thread: LM5121,

Hello,

Can the top FET be reversed in a TPS43061RTER based regulator circuit to prevent the Vin from bleeding into Vout via the body diode?

Down stream of the TPS43061RTER, I am using a TPS27S100APWPR to drive a solenoid.  During short circuit or over current (3A) testing at the solenoid, I am getting large current spikes that is tripping the power limiter circuit at the front end of my design.  Do you have any other suggestions to resolve the current spike issue?

Where can I send in my schematic for a design review? 

Thanks for the help.
