I am sure some have managed to do it.
What makes it difficult is anyone planning to fake their death is probably doing so for a reason that will make the authorities take a very hard look at their disappearance/death because of the motive involved.
If you have no reason to fake your death, than doing so becomes much easier because any investigation would be rather superficial.
In either case, I think a key to success is to try and create your alternate identity first, ideally, year(s) in advance. Establish some history, activity before the date you kill off the old you.
Of course doing so without leaving a trail of breadcrumbs back to your old identity will be tricky and pose risks.
