  Wedge absorbers are needed to obtain longitudinal cooling in ionization
cooling. They also can be used to obtain emittance exchanges between
longitudinal and transverse phase space. There can be large exchanges in
emittance, even with single wedges. In the present note we explore the use of
wedge absorbers in the MICE experiment to obtain transverse-longitudinal
emittance exchanges within present and future operational conditions. The same
wedge can be used to explore "direct" and "reverse" emittance exchange
dynamics, where direct indicates a configuration that reduces momentum spread
and reverse is a configuration that increases momentum spread. Analytical
estimated and ICOOL and G4BeamLine simulations of the exchanges at MICE
parameters are presented. Large exchanges can be obtained in both reverse and
direct configurations.
