I'd say go for it. Stem plants are cheap enough to replace anyway.
I'm doing the same thing. I bought a bunch of stem plants for my sister and swiped a few of each type to see if anything would survive. All I know about my light fixture is that it has 21 LEDs. No idea what the output, spectrum, etc. is. My tank is only 6 gallons, so I think it is shallow enough that things are working.
I used to have a very deep 45 gallon corner tank with a 65W CF fixture. Rotala grew for me but they were "leggy" rather than fully leafed. Most of the leaf concentration ended up being in the upper parts of the tank and I didn't get many runners or new plant growth.
