Using both 'Bitlocker' and 'VeraCrypt' at the same time on one partition

[Cyanide2x4]

Is it possible to encrypt a particular drive/partition using Bitlocker and then using VeraCrypt? Are there any advantages to doing this?

The assumption is that the password used for Bitlocker is completely different than the one used by VeraCrypt and in both cases the password is more than 25 characters long.

Does this add anything to the security of the partition? And is it at all possible and risk-free? Can this make particular problems arise due to any inference of two encryption programmes used on the same partition?

Possible: yes
Good idea: no.

First and foremost if they have the ability to break one level of encryption in any sort of a timely maner then they can break both.
Secondly, running 2 layers of encryption will tax your CPU, slow down everything, and greatly increase risk of corrupted data.
