What other models of, or vehicles, would be helpful?

What if one of Srila Prabhupada's diciples started a simplified version along this model for example.

A bhajan/kirtan center or hall with just constant chanting and classes being broken only for prasadam BUT WITH NO FORMAL DEITY WORSHIP, only a nice picture of Panca Tattva and the devotee.

Would that be considered somehow less then the parampara standard? Or even unbonefide entirely?
