let me try to paraphrase so i can understand your answer better, ok?
the satellite site is the perfect match widget domain page, and it is branded to look uniform to the main site for user experience visual uniformity. It has unique content, and some how has many links pointing to it ( how did you perform that feat i wonder?) - with directories or blog articles pointing to those perfect match domains?
so its right now, in the short term, a click from the perfect match domain to the main site, with anchor text coming from that, as well as the prior link going to it, but later, you will change that and just do a 301 redirect to the main site, so user experience will be only the main site, yes?
Using the 301 redirect you may lose about or around 10% as i understand it, link juice.
And important follow up question, when you mentioned building trust, how exactly is that accomplished? By having good content on the main page certainly, and perhaps all the sorts of pages that build trust - company profile, terms of service , faq pages?
Add finally, when you do the 301 redirect ultimately, you will move the content over to the landing pages you are sending them to?
thanks!
