It is very difficult to discern what you are asking -
If you are asking "Can I have 2 different sets of nameservers, with different information described in them for the same resources, where the wider Internet can access both of them simultaneously" - which appears to be your question - the answer is no.
It is possible to sub-delegate, ie have the nameservers for, for example, example.com point to one set of nameservers, then to subdelegate www.example.com to another set of nameservers.
