Would an outbound ACL be an overkill?

Hello All, today I wanted to block traffic from a couple of untrusted IPs on my ASA firewall, which I did by creating an inbound ACL applied to my external interface. The ACL specifies to block any inbound IP traffic from these addresses to any of my networks.
Would it be an overkill to create an outbound ACL applied to my inside interface that specifies to block all traffic from my LAN to any of those IPs?
One of the ACLs that I have notice in my configuration is an implied one applied to my inside interface that permits all traffic from my LAN to less trusted networks, I believe this ACL is a default one. Would I be overwriting this ACL if I apply this ACL?
