Not sure how fast your KA is, but on a low-power motor the added surface area most likely does not give any benefit, so all you are doing is adding extra rotating mass, which will only make the KA feel even slower than it already is.
If you are doing it because you are poor, then you are better off just having your flywheel resurfaced and buying a new OEM-replacement clutch. If you are looking for performance, buy a grippy clutch and a lightweight flywheel.
