Two LBs or just 1?

Running mostly Nickel and dollar formations, so I never have more than 2 "linebacker" spots on the field at all times. 

I've been using one linebacker and one safety in these formations. However, with the new lurk artist ability + having to stop the run with linebackers instead of safeties with the latest update, would I be better off to just use two linebackers and let my safeties play their natural position? Here is my personnel if it matters

MLB1: Ray Lewis

MLB2: Channing Crowder (currently an 85)

SS1: Eric Berry (89)

SS2: Pola-Moa 

Right now, I'm running Berry at SS, Pola-Moa at SUBLB1 and Lewis at SUBLB2. Would I be better to move Pola-Moa back to SS and just use Lewis/Crowder to get another linebacker on the field?

I have Crowder and Te'o and those are my sublbs. I stay away from putting safeties there for that reason you mentioned. They do fine for me coverage wise and they are a benefit on the run for sure.

Honestly, two is probably the way to go to if you can afford it. Though you probably want one of them to be good in coverage if you mainly stick to one user. 

If I recall correctly, all or most of the MCS competitors were using two lurk artist LBs which should give you an idea of how good the pros think it is.
