How do you create landing pages with different domains?

[LovingatYourBest]

I am wondering how do I create landing pages with differing domains? We recently acquired some other domains that will hopefully help with our SEO, Key Word targeting. I understand how to create the landing page but I don't know how to link it to our other domain. I was thinking about a  rel canonical but will that defeat the purpose of the landing page, in terms of ranking? I guess the issue that I am facing is when we start up these new domains they will not have the Domain Authority or the Page Authority of our main site. I would like to try and get them ranked organically as well as PPC.

Thanks.

What's the point of the new domains in relation to the primary domain? Are you planning on using them to cover niche's unrelated to the main site? Are they different businesses branching off of the main company (subsidiaries on the main)? Depending on how you're planning on using them, there's a variety of different things you can do. There are a variety of ways to solve a problem so depending on what your goals are, the community may suggest something different.

Share a little more about what you're doing (you don't need to give away full specifics), and maybe we can come up with a good way to use them.
