Hi Jonjongot,
Welcome to Sony Community!
We don't recommend an upgrade on any VAIO laptops because they're integrated with each other. We can't guarantee the outcome of the upgrade. In addition, replacing any parts might do more damage to the laptop.
It may be possible to achieve what you mentioned above but Sony does not support or provide assistance for this.
For further assistance regarding your concern, please contact the Sony offices/Sony representative offices nearest to your place of residence in Asia Pacific region http://www.sony-asia.com/countryselector.html?hpid=countryselector:AsiaPacific. Due to proximity, they are in a better position to respond to your questions or concerns.
Regards,
Jen
