I went through my parts box today and found a TAC Clone Commander as well as a TVC AOTC Clone Trooper.
Off came the pauldron and the belt/kama from the Commander and went onto the Trooper. I also added a spare rangefinder to the Trooper's Phase 1 helmet to create one of the Clone Commanders who received ARC Trooper training after the Battle of Geonosis.
I like the combination of the Phase 1 armor which starts to show individual touches by adding coloured markings, pauldrons and kamas.
Here's Clone Commander Arrow:
Another figure I like as a basic figure for customs is the Gelagrub Patrol Trooper.
On this one I took the softgoods kama and gunbelt off and replaced it with the belt/harness/shoulder armor of a Commander Neyo figure.
I gave him the rifle from a Marvel Universe Cable figure, but he looks sharp with a DC-15 rifle or carbine, too.
Here's Clone Corporal Aitch:
