The Sluice Box can be used as an early solution for resource gathering, but I'm having a problem, because at the current state in the modpack you won't be able to obtain an iron bucket. After some testing I realized that no other buckets from other mods works on the Slice Box. (tested with Ceramics an Clay Buckets)

Would it be possible to add support for those?

yeah, having this issue as well, was just going to report that, accepting any fluid container with water in it, would be great.
