Making yourself more valuable to the band is never a bad thing.
As much as I like being in a band with a good vocalist I expect them to show up with their "A" game as often as I do. And if I can make it there and do my job AND theirs at the same time well enough for the band to settle on both then it should be a solid kick in the pants for them.
The band I'm in now I came in as JUST a bass player. Now I'm singing about 1/4 of the set. Everyone in the band knows that the option is there for me to expand, especially the lead-singer. Doing a gig without her isn't that much of a stretch. And even with that the band knows that I have a repertoire of three sets of material that I can play and sing on acoustic without them.
Given the chance to choose I would much rather play bass. But if the lead singer genuinely can't handle the vocal range then so be it. Let someone who can take the lead.
