How large is your fullerene? If it's something like a C60 couldn't you
just randomize them outside of XLEaP and then enter those in manually by
editing the molecule? That assumes you aren't making a large number of
them.
But honestly, that seems like a very sketchy way of getting what you want,
what is the basis of those random charges? I think to do that properly
you'd need to get your fullerene working with a polarizable forcefield,
such that your polar compounds get trapped in a more physically meaningful
manner (that is, through dipole induced dipole interactions). I've no idea
how difficult it would be to add the fullerene properties to something like
Amoeba or DFTB.
Just my opinion.
