I dont really need projection to this space and I dont know of any reason why this would be needed. These spaces arise as intermediaries in DG schemes and one does not really need an initial condition for these variables. We can set zero initial guess for the trace solution. But in a nonlinear problem as in compressible flows, we need to set a physically correct (positive density/pressure) initial condition for the trace variables. So interpolation should suffice for this purpose.
