I am relocating the comm and mic jacks in my Lancair to a position
behind the pilot/co-pilot seatback and so the comm and mic cables need
to be lengthened. Any suggestions here for what would be the best
method for splicing additional length to these cables and also
maintaining the integrity of the shields?

Strip back 3 inches or so of outer insulation
on cables to be spliced. Pull conductors out
of the shield as shown in , , ,

Lap splice the individual strands as shown
here . . .

Actually, you don't even need to "bulk up" the
joint by wrapping the strands, you can simply
lay them parallel and solder as shown on page
84 of . . .
http://www.aeroelectric.com/Reference_Docs/NASA/NASA-STD-8739p4c4.pdf
Once the individual strands are joined and
insulated, overlap the braid pigtails a half
inch or so and lap solder them too. No
individual insulation is called for on this
final joint.
Put a piece of heat-shrink over the finished
splice.
Shielding of these wires has a vanishingly small
benefit for noise mitigation on these wires.
Don't worry about loss of shielding integrity
at the joint.
