Anyone know if there is something equally simplistic and universal than LVM that allows for storage policies?

Aka. instead of needing equally sized disks to get something like RAID-5/6 but with an arbitrary amount of drives in arbitrary sizes? (Without the capacity capping).

For now say like I'd have something silly like this:
4x 5 TB
2x 20 TB
20x 1 TB
1x 500 GB
+ change

Goal:
* Encryption at rest
* Tolerates 2 drive failures without any dataloss at all (by more partial)
