Why cheat rather than fix the problem?! Personally I would not use e-steps as a cheat as that affects accuracy, which of course may not be important to you. Anyway it is far too complicated compared with other options, as @gr5 says Flow is a quick easy cheat. But it is still cheating in my book; fix your problem and I am sure you will get more consistent better looking prints
Yes, changing the diameter is a way to cheat. You set the diameter smaller to get it to extrude more. The area is the square of the diameter so you have to adjust by the square root of what you what changed. For example if you want to increse by 10% you need to find the square root of 0.90 times the current diameter.
However it's even easier to set the "flow". In cura you set the flow to 110% and it will extrude 110% more than nominal.
For setting steps/mm you can follow these instructions here which should be identical for creality printers versus ultimaker printers:
