That would be very nice.  I've been using (for input from sc8 file to a
complex flowgraph):

UChar to Float -> Deinterleave => Float to Complex

Since my samples are unsigned chars, this gives me an offset of
approximately 128 that I can correct with Add Const either before
Deinterleave or after Float to Complex (where it is 128+128j).

Unsigned sc8 is the primary data format used by HackRF, so this may be
interesting to other HackRF users.  The conversion is handled by
gr-osmosdr when communicating with a HackRF directly from GNU Radio, but
files transmitted or received via the hackrf_transfer utility are in the
unsigned sc8 format.
