      Normal loop with changing bytes wont work because u can cut end of one instruction and beginning of second (the bytes may fit not only the MOV instruction), you need something that will have built in disasm

      i mean thats some bytes may be your instruction, lets say 5, but its also possible that 3 bytes are end of one instruction and 2 are beginning of next, and than patching it will crash the app. You need something with disasm, what can recognize the instructions. By the way it looks like specific command, how many times it appears? Maybe better idea is to simply copy few addresses?

      Just assemble it in Cheat Engine and copy the bytes of the instruction. Then use the Trainer class by Cless and write to that place. As easy as that.

      [ESI+16C]

      Another way is to find a way to get what ESI holds and store it. Then do your magic once ready.
