Myself and Nick McCarthy have published and presented on VOLK. Here's
a pretty good overview video of using it:

To answer your question, yes, building a vector like that is
acceptable for use with volk kernels as long as you are using the
correct data types. Be aware of alignment requirements, though, which
the link above explains.
