Is Tank/Dps Rakan possible?

My boyfriend wants to start playing Xayah/Rakan botlane (He even bought us matching skins) but here's the thing. I'm the one playing Rakan and the issue is that my BF has only played league for 2-4 months at Max so he's still in the learning process (He really likes the role of adc so im trying to teach him). I've been playing for 6 years and got the rank of Master on my main account, but never really seriously played Rakan until now. Is there any possible build that may help me do the most damage early game, while also be able to sustain a good amount of damage for him? Or is there any tips you'd give me as a Master support playing with a currently iron adc?

Really appreciate you Rakan mains <3
