Depending on what you expect this idea will likely be shot down. You cannot do 'fancy' things like disabling things in game when you're using reflection.
Try turning off paint overlay and hiding to tray. Both have been shown to reduce CPU usage. P.S. The reason Cloud put fancy in quotes is because he's nice and didn't want to say detectable instead to be kind to our competitors.
To follow up at @Cloud his post. There were clients who had this in the past, but there is a reason why They stoppen using it it's causes many bugs
Injection isn't necessary to produce a paint, it's effectively just an overlay. Methods such as reflection can be used to obtain the necessary information such as stats/xp.
