Arcanine w/ Bite/Crunch possible attacker into Gengar I solo raid attempt?

I have two arcanines at 91% IV, currently sitting at lvl 28. Both have Bite, and they originally came with Bulldoze, and I TM'd them to crunch, because bulldoze was too much to look at.

My Machamp solo team is almost ready to deploy and I'm looking ahead a couple days and would like to solo gengar as well, mainly because getting people excited in my town is not easy, even if it only is one more person. My gengars to date are at best subpar so I'm loooking to keep hitting gengar raids till I get one with decent IVs. I think gengar will be a important factor in legendary battles to come.

My other team members for this solo raid are:
87% IV tyranitar with Bite/Crunch
2 98% IV Alakasams Confusion/ Future Sight
1 89% IV Espeon Confusion/Future Sight

As of now these guys are all four days away to being powered up to lvl 30 across the board. And a second tyranitar lvl 30 will be hard to come by for me. Additionally, I'll be lvl 34 tomorrow so I can power up everything including the tyranitar further if need be. I'm still not certain how defense stats calculate to the opponent pokemons attack stats. Gengar is better than Arcanine but Arcanine has no other weaknesses to Ghost; Bite is a fast attack maybe slower on energy, but far better on cool down in comparision to snarl. Any input would be greatly appreciated at considered.
