You're probably better off with Fomapan 100R or Filmotec Orwo UN54 both are designed for reversal processing and can be used for filmmaking especially Orwo UN54 which actually is a motion picture film stock and a very good one at that. But nothing speaks against using Tmax in the Lomokino (Exposure time is ca. 1/100 and it has three aperture settings at least according to the Lomographic guys) use f8 and be there at least in sunlight
