Will The Watchtower Play A Part In The Justice League Movies?

There was an interesting thing that happened on Jason Momoa's Instagram account.  He uploaded a video of the workout that he's been doing to prepare for the upcoming Aquaman movie, and wrote "Watchtower" in the caption.  Now this doesn't really mean anything on the face of it, but why write "Watchtower" in the caption?  Is he alluding to something that may be coming to the DCEU, or is that what he's calling the gym that he's doing his workouts in?

The Watchtower was first introduced in 1997, and has either been featured as a space station or a base located on the Moon.  It has made appearances in different animated features, as well as the Justice League Unlimited animated series.  Every time it's been shown, it's been used as the Justice League's base of operations.  Now here's the question...but first, ***SPOILERS AHEAD!!!*** for Batman v Superman: Dawn of Justice!

At the end of the movie, after Superman "dies" fighting Doomsday (let's face it, he's not going to stay dead!) Batman tells Wonder Woman that he's going to round up all of the other metahumans that he saw in Lex Luthor's secret files to help protect the Earth in Superman absence.  It would make sense for them to have a base of operations so they can coordinate operations.  The problem is...Batman dosen't know if any of the metahumans will be willing to join forces.  We know that they'll eventually become a team, but he can't be so sure.  At least, not sure enough to justify building a huge base in space or on the Moon.  Why bother with it if they refuse to join?  He could just as easily work out of the Batcave if it ended up just being himself and Wonder Woman.  Plus, how would he build it without alerting the military or world governments?  The only way that he'd be able to do it is with alien technology that he doesn't have yet.

So there are two options if they are planning on bringing in the Watchtower.  First, they refit an alien ship that they get at some point in a future DCEU movie, and turn it into the Watchtower.  The second way they could explain the existence of the Watchtower is that during/after the Justice League movies, Batman is able to copy the technology of the Boom Tubes that Darkseid uses and using the money from Wayne Enterprises, is able to build the Watchtower using the Boom Tubes, eliminating the need for rockets and alerting the military or other world governments.  This, of course, can only happen if they end up using Darkseid as the big baddie in the Justice League films, and not Brainiac.

So what do you think?  Do you think that we'll get to see the Watchtower at some point in the DCEU?  If so, when do you think we'll first get to see it?  Leave me your thoughts in the comments section below.
