Sugestions on my future dehya build and comp?

I'm planning to get Dehya with the character selector, so i want everyone's opinion on the build and team i planned for her. For starters, i want to focus on using her as a main dps. I still plan to use her on my Lyney's mono pyro team, (for interruption resistence) but still using the dps build, even knowing it won't be really worth it if she's not using the tenacity set.

For the team, i wanna make it a melt comp, since it's the only reaction i don't have a team for. (i know it doesn't matter, i just think it's fun.) The team i have in mind is Rosaria, Furina and Charlote/Bennet. I'm still not sure about that support slot, since Bennet would be perfect, but i don't know if Rosaria can aply pyro fast enough to keep up with Dehya, so i thought Charlote would be good to have more cryo application. (I don't have Kazuha to swril, and don't know how good Sucrose or Lynette would work).

For the artifacts set, i was going to use Vourukasha's Glow, for the insane burst dmg bonus. And using the standard dps build, ATK/Pyro DMG/Crit, while trying to get good hp rolls on the sub stats. And for the weapon, i'm planning to use the Wolf's Gravestone that i have lying around for while now.

So, any sugestions about the build and team comp? I know she's not a good dps at C0, but i like the character a lot and want to use her in more teams than just lyney's. (And i already have my Thoma full em for burgeon and burning)
