Yes it can be done. Pros are easy configuration and less devices to manage. The only Con I can think of is there will be no pre-filtering which isn't a huge deal anyway. Routing is very straightforward. Assume that your ISP is giving you a range of IP's of 192.168.1.2-5, with .1 being their device and your default gateway. The command would look like this-

ip route 0.0.0.0 0.0.0.0 192.168.1.1

Hope it helps.

Yes collin is right you can do that and check out the below sample configuration of ASA 5505 configuration with simple default routing.
