Soldering this twisted lead, if done properly, will not heat the insulation of the insulated lead and will not compromise that insulation.
Also making a solderless connection as you describe, will not provide a perfect ground.(OR a lasting connection)
There are two methods to create a proper electrical connection. Mechanical crimp, preferred in most cases, and soldered (when properly completed)
Wrapping a conductor around another conductor and using shrink tube to hold it in place may work for a short term but time and nature will form corrosion between the two conductors reducing and/or preventing the connection integrity.
For lasting results, always either Crimp using proper avionics crimping tools or solder with proper heat and solder composition.
