You could convert each signed integer to a modular of the same size
using Unchecked_Conversion.  And I think your code already knows how to
convert that to an array-of-8-bytes, with the right byte ordering.

Or, unchecked conv signed to modular of same size, then use a normal
type_conversion to convert to a "mod 2**64" type, then unchecked convert
that to array-of-8-bytes, then apply a byte-swap procedure to that
array.
