It would be well-suited for extreme downscaling, but much faster than Arearesize.

fmtconv has a box kernel

Requires AVS+; doesn't work with regular AVIsynth

With old AVS you can try GaussResize with the very low p-param. Also you not describe how much 'support/size' of the box do you want.

In AVS 2.6.0 sources I see support of GaussResize is not very small of 4.0. So I think it is 4.0x2 output samples width at least. And 4.0x2xdownscale_ratio of input samples. param is clipped to 0.1..100.0 so for box-like kernel p should be 0.1.
