I have been experimenting with different strings now...and I was thinkin of restringin my backup bass( I have 2). I don't have any Five-Strings but wouldn't mind having some of the capabilities of a Fiver

would it be feasable to string by bass B E A D instead of E A D G??

any advice?
Yup. All you need is to maybe file the nut, though you probably won't, and do a slight intonation change.

Maybe check the neck relief.

Apart from that, it should be good.
