Sounds a little selfish to me, writing the bass parts. You need to talk this over with the rest of the band. If you say, "Ok, were putting everything under his and my name," I wouldn't be suprised if the other members throw a big fight or walk out. I understand you just want to protect your interests, but you might want to re-think your plans.
