No, It is not possible, It was 2 or 3 years ago, But not anymore, If you want to save your SHSH, You should use a Program like TinyUmbrella to save the SHSH Blobs for the Firmware you are on now!

Tiny umbrella does not save SHSH for the software you are on now. It saves SHSH for the software that Apple is currently signing. eg if you on 4.3.2 and you save SHSH today you will save 4.3.5.
However, there is a program (strictly for Windows) that allows you to save the SHSH for the current firmware you're currently running even if Apple isn't signing it anymore.
No, you cant downgrade your firmware version without shsh blobs.
iFaith pulls your shsh blobs out of your current installed firmware but that would only allow you to reinstall the same firmware version, not downgrade.
