No, that's fine. I talked to a DM I knew a few years ago. He happened to come in to work, and I asked him his opinion, since I figured that he was one of the people who I knew would allow that combination, and had him explain why he'd allow it. After we talked, we came to a conclusion that it's basically DM fiat. If it doesn't break the campaign world, and the PC actually pays the material component cost, and you'd like to see the deceased PC brought back, then it's a viable combination so long as it doesn't get abused, and that the NPCs can use it as well against the PCs. I thought that was fair. Your character sheet has a set number of gold set aside for material components. So long as this combination is used on a regular basis, I'm willing to allow it for this and future games.
