Your addressed interfaces on a given ASA must all be in unique subnets. So you will not be able to configure both M0/0 and M0/1 in the same subnet.
That model of a firewall is almost always setup in an HA pair so the standby unit's M0/0 could be connected to switch 2.
You could also setup M0/1 in a unique subnet and create a new LAN for that on the switches.
One other option is to allow management access to the ASA via the inside interface (restricted to access from your designated admin networks if you like).
