Studies of a scintillator-based muon system have been going on since 2001 under the leadership of Gene Fisk and Paul Karchin and are summarized in:
NIU personnel have spent the past twenty years working on muon detection at hadron colliders. We recently have begun studying muon detection issues at a possible future electron-positron linear collider. Many of the LC issues are similar to those at hadron colliders with a LC having the advantage of not having the large QCD production rate as a background to new rare processes. This means that a LC basically does not have to be concerned with triggering.
Muon backgrounds in the central region come from either pion or kaon decays in flight or from hadronic punchthroughs. Decays in flight depend on the distance to the calorimeter and decrease with particle momentum. Punchthroughs are due to hadronic energy leaking out the back of the calorimeter and could either be a non-interacting hadron, actual hadronic debris in the muon system, or a muon produced by one of the tertiary pions or kaons in the hadronic shower. If the punchthrough is due to an exiting muon, that muon typically has .05-.10 of the incoming hadron's momentum. The punchthrough rate increases with momentum and decreases with thickness as seen in:

Arthur Maciel is using the SLAC LCD/JAS framework and geometry to study of hadronic leakage into the muon system ZZ events.
