You should get face to face advice regarding this, see
Where to get advice? Apart from the fact that you would be making a new claim, which means re-qualifying for ESA and only being paid at the assessment rate until you do, you would need the DWP to re-confirm that the work you are doing qualifies as Permitted Work, which they may not do until your assessment is complete.
There is also the issue that you might be seen as intentionally depriving yourself in order to receive a higher rate of benefit.
