No. Relatively small perturbations, including relatively slow pitch changes, could start a little bit of slosh going. If the slosh frequency is resonant with the lag in the control system, then it could quickly become a lot of slosh.
Is there any possibility of doing a test while suspended from (e.g.) a crane before doing the free flight? This would allow working out of some of the complex issues like slosh without too much risk to the vehicle. Downside is that it'd probably be a bit expensive.
