[Q] Can I/how do I install Knox on MOAR v6.2? For Mobile@Work

In normal circumstances I would have no interested doing this or even be asking this question, but I recently started a new job that uses a Mobile Iron app to manage work email encryption for BYOD. The Mobile@Work app relies on Samsung Knox for (at least for some amount) of the cryptocode on the Galaxy S5. Since MOAR v6.2 doesn't include Knox the app wont configure and validate. I am very happy with Moar v6.2 and would rather stay on the custom rom than flash to a stock rom. I've already spoken to my coworker who administrates our side of the MobileIron platform and he has no solution from his side. The APK from the google store automatically detects your device and which crypto it wants to use. I know MobileIron has other options than Knox for android devices. I'm waiting to hear back to see if one would be made available to me, but I doubt it.

So the options I see are (placed in ordered in preferably)
1. Add Knox to Moar v6.2 (I don't the process to do this or if it would break Moar v6.2)
2. Try another custom rom from your suggestions that includes Knox. (I've only used MOAR on my s5 so far, so open to try other roms)
3. Go to stock firmware (Least Prefered)

Now besides the options and my personal preferences, the real importance is that I don't fully side-skirt the security in place for emails. I'm hoping to have my cake and eat it too, but I'm not sure if that's possible here. If it isn't I'll just have to go back to a stock rom even if it pains me. Thank you in advance for reading and your advice
