No. GENERALLY not, and no with MegaRaid. There was once one that coudl do that (RaidCore IIRC) but that technology is not available anymore.
As RAid cards function as independent sub-controllers you can not have a Raid volume spanning 2 of them.
You can do that in the OS though.

Just bear in mind that if you do that, you can end up decreasing your resilience, by increasing dependencies.– SobriqueAug 11, 2014 at 9:38
