Mannyrock, if you wish to ignore the advice given above by several experienced posters, that is certainly your privilege.
While I understand the problem of connecting and bending 14 gauge stranded wiring, I would note that running a single straight length of 14-gauge is probably less overall strain than several sets of 18 gauge
If you may someday add electronic control, such as DCS, your system may complicate matters.
If heat becomes a wiring issue on a layout, you either have a short circuit somewhere or wires are too small. The issue is voltage drop, not heat, and it cannot really be anticipated by applying Ohm's law.
