I've heard people mixing things like Seachem flourite with small black gravel and it working fine. If your using eco-complete you may see some seperation with the bigger gravel getting to the top, but that would be over time.
It would still work, IMO. So go for it
You can make just about anything work as a substrate. It's just a matter of your ability to work around it enough to keep other factors inline with the substrate/water parameters.
