  The dynamics of the torsion-powered teleparallel theory are only viable
because thirty-six multiplier fields disable all components of the
Riemann--Cartan curvature. We generalise this suggestive approach by
considering Poincar\'e gauge theory in which sixty such `geometric multipliers'
can be invoked to disable any given irreducible part of the curvature, or
indeed the torsion. Torsion theories motivated by a weak-field analysis
frequently suffer from unwanted dynamics in the strong-field regime, such as
the activation of ghosts. By considering the propagation of massive,
parity-even vector torsion, we explore how geometric multipliers may be able to
limit strong-field departures from the weak-field Hamiltonian constraint
structure, and consider their tree-level phenomena.
