Mango plantation with Coconut & Arecanut plantation

Hello team,
Our 2 acre farm in Dharwad-Karnataka has Mango as prime crop-100 plants. Can we have Mango+Coconut+Arecanut farming combined? with each plant being maintained at decent distance. Can we add any other longterm fruit plants to this list? …please advise. Mixed plantation for better space usability.
We are uable to get workers in the farm ,hence cant grow vegetables on rotation.
Any other plants combination giving better yield and resuts are also welcome.

Thanks in advance,

As per my knowledge, you should not supply water to Mango after flowering for few weeks, but coconut and arecanut needs frequent water supply. So please check with some experienced.
