I think we'd like to have an element for that, which would have a
property that takes an array of channel positions for the input and
then accordingly reorders the channels and puts the correct channel-
mask on the output.

But for now, doing it with deinterleave and interleave should work, you
just need to make sure that interleave puts the correct channel-mask on
the output caps. It has a property for that. Or alternatively you could
put a capssetter before every input of the interleave and set a
channel-mask with a single bit for that.
