Is it possible and worth the effort? If i turned my laptop into a miner only, would I be able to generate enough BTC to do anything with?
Not a good idea. This will force your laptop to work harder and will shorten the laptops life span. Laptops are not designed to this kind of work and stress.
And that's not mentioning that, beside possibly damaging your laptop, you would probably do so before you break the dust limit payout on any pool. That laptop would be better off running a USB Stick like the GekkoScience usb stick and run the lottery with it.
Laptop do fine as controllers.
