If you want to have that in a cheap way you can simply wrap your searchlight'able measure with another custom measure. Say you are doing a cross-validation in the spheres: cv = CrossValidation(...) you compose a wrapper: m = MyMeasure(cv, covariate_ds) that custom measure implements _call() to hstack() the incoming dataset (which will be one particular sphere) with you covariates. Afterwards it will run the same CV as before. That should do it.
