Possible to replace dialer in stock rom?

view story

http://forum.xda-developers.com – So i have some long standing issues with the GS3's dialer, i think its slow, buggy, counter intuitive and lacking customization. My biggest issue is an inconsistancy when moving from the actual dialer to contacts, i posted about this a while back: http://forum.xda-developers.com/show...php?p=29992041 Ideally i wish i had aosp dialer or the dialer i was playing with in CM10. So my first question is: does anybody know if its possible or if anyone has replaced the dialer on a stock modified rom (i'm on synergy r77). If it hasnt been done yet but might be possible can someone point me (HowTos)
