Is it possible to configure Ether-Channel on an ASA Firewall, and if so how? Also, is it worth it? Looking for Redundancy
For example, having 2-3 Ethernet lines feeding a switch from the ASA. Thoughts on this?

I do not understand parts of your follow up question. The part that is clear is what other ways. So another way would be to configure multiple interfaces (on an ASA) connecting to multiple interfaces (on switch(es) as EtherChannel and configure it as a trunk carrying multiple vlans (so you could have a vlan for Inside and a vlan for DMZ both carried over the EtherChannel). Another possibility is to configure interfaces on 2 ASA (configured as a failover pair) as Etherchannels connecting to interfaces on switch(es)

Hello,
Etherchannel on the ASA is certainly possible. Check the link below for details:

For link resiliancy always suggested to use link bundle,(for high throughput and link resilinacy) where possible to get advantage of it.

I configured ASA Ether Channel for a customer. They were pleased with how it worked and thought it was well worth doing. It provided quite effective redundancy.

That should be one way to do it.
