Hello Vijay,
As you say you can use another one, That's correct but the thing is that the management IP is not only used for management purporses.
That's were you are missing the point.
That IP address assigned to the ASA as a whole will also be used for ARP requests when the ASA does not know where the destination hosts lies and it's not on the same subnet than the ASA.
It will also be used as a source for packets going to a syslog server, AAA server, Netflow server, SNMP server and any packet that the ASA will need to create so with that in mind the routing of the network will need to be changed to work with this.
If you get to accomplish that the routing of the network works with a different Management IP address on the transparent address then you can do it. I can ensure you I have seen this scenario before working with no issues at all bud.
