We show how the hopping parameter expansion at order \ensuremathκ2 and \ensuremathκ4 can be exploited in the simulation of lattice QCD with two flavors of degenerate Wilson fermions. A natural extension of this idea is a ``UV filtering'' by using rooted polynomials. These approaches can be easily combined with, for example, mass preconditioning. First numerical tests are performed for the Wilson gauge action at \ensuremathβ=5.6 and \ensuremathκ=0.156 and 0.1575.
