No. The starter solenoid gets power from the starter switch, leave that one alone. The ground connection to the solenoid is via the safety circuit. The starter is grounded through the clutch switch directly or through the neutral switch using a diode (this just lets the neutral light work properly, without it the neutral light would be on with the clutch in).
So connecting the 2 wires to the clutch lever switch disables the safety system and the starter motor will run even with the bike in gear and clutch engaged.
