I don’t think so, since coil setup would be different, even though the size is quite similar. You can however get a spot lamp fitted, that way you will get additional 35 or 55w and that too without tinkering with the wiring or coil, since it can be directly connected to the battery.
Ps. If you decide to do that, don’t forget to remove it each time you take her to service station, else you will end up with a void warranty.
