Yes, mixing them together would be fine for growing plants. However, you will soon find that attempting to layer them will not work as you intended.

The sand will not stay on top of the Eco Complete for long, and with time, it will sink to the bottom.

Any recommendations then of stuff that might work a little better but still have that sandy kind of appearance and grow plants nicely and support them?

I have used Flourite Black sand type with good success.

I've recently been using pool filter sand at $10 for a 50lb bag. Make sure you get one without chemicals added and give it a good rinse or two before using.

I have Discus w/pool sand and Eco-Complete mix up it only needs to be 3" deep and my plants are doing good just add some root tubs and make sure you keep up on your water changes and your Discus will be happy. Check out SimplyDiscus.com for any info or help on Discus. GOOD LUCK
