Nothing personal but trust me man, if you are trying to punch and kick simultaneously while in trapping range, it may work against some, but anyone with good lat sau jik chung training and the knowledge to eat space will put you on your ass 99.5 % of the time.
Chi gherk or to use a more technical term- using your legs- is entirely possible in closer ranges. Thai boxing and judo provide ample competitive evidence for this at ranges just inside where most chi sao is performed, and closer.
If you are able to maintain structure, pressure, and the ability to change while constantly/frequently having a leg free to act, there are numerous opportunties to use leg actions in combination with hand actions. Developing yourself to the point where you can do this takes some work, but stems from working on 0/100 based structure, which moves your central axis from directly between your feet (50/50, 40/60) back about 4-6", making it more likely and easier that when you press with the arms, the front leg will press at the same time, breaking the other person’s structure on the low line (a leg split in greco-roman wrestling). From this core mechanic (lead knee and elbow pressing), other things can develop.
Frankly, I usually don’t bring legs into chi sao with people who don’t train them regularly because most folks have a meltdown when you start kneeing, stepping on feet, and sweeping them, and take it kinda personally.

I guess it depends on your definition of Chi-Gerk. If you mean the version where the legs stick together all the time, there is a great chance for the fact that you’re training “chasing legs” as opposed to using the legs to “eat space”.
Chi gherk (in WT) is the set of skills from stopkicking on the upper thigh or pelvis, to leg checks, to sweeps/offbalances off of leg checks, in to pressing their hip with yours. There are some formal chi gherk drills taught at upper levels which refine some mechanics working wooden dummy apps and Biu tze counters to them. These are probably derived from the chi gherk drills (cycles) constructed in HK in the 50s, which are appearantly based on much older loose applications (Rene, wanna chime in here?).
