Moon Blade

[Solace of Tides]

I just have a quick question regarding the Moon Blade spell from the Moon domain:

Are you able to (through either Triadspell or DMM, etc) have more than one of this spell active at the same time?

I was thinking about running TWF with these, and wanted to make sure this would be legit first.

(P.S. would DMM even allow you to cast the spell more than once, since it would take turn attempts and not the spell slot?)

I see nothing in the spell description that would disallow using two at once.
