In short, no. For the time being, external scripting might be
advisable, whereby you loop over the configurations generated
by your Namd-cuda run, calculate U(λ), modify your parameters
and calculate U(λ+δλ), prior to averaging. This is tantamount
to a single-topology-like paradigm. A properly written script
may give you the illusion of estimating the free-energy change
on the fly, the main computational effort being the generation
of the ensemble of configurations at λ.
