Theoretically, yes...
The thing is, we don't even really know if A. cyclops contains DMT, nor what else it may have. I can't find a single published analysis of it, and in the Acacia info thread by nen there are only some people extracting either oils or crystals that smell like DMT, but no confirmation even with reagents AFAIK, not even a positive bioassay talking about the effects.
Please proceed with caution testing plants with unknown alkaloid profile. I'd test with
TLC or at least some reagents to see what it might contain, before considering smoking it or whatever.
That being said, going back to the original question, IF it does contain DMT, it can also be that your naphtha is not saturated enough, so you can try evapping it further before freezing it. Lastly, sometimes DMT forms oil instead of crystallizing, so IF it was DMT, having it as an oil isn't necessarily bad.
Test it out and let us know!
