You appear to be working under some misconceptions.
The fist one I want to address is the notion of PageRank of a domain. Google has not made these metrics available in quite a few years. If you are getting this metric off of a website, please ignore it. It is garbage.
The second is that creating a page with links from one domain to another will boost search performance. If there are no links to the old domain or links of little value, any link you create will have little or no value.
Additionally, you do not want to appear to be making links in an unnatural manner.
The old notion of a PR 6 site with 2 links passing PR 3 for each link has always been incorrect. This is not how PageRank works. Without getting into details, if you expect to pass value from the old domain to the new domain, you will be disappointed. More or less links do not help.
Google will not reward a single link from a home page where there is no site. This could be seen as spam. Google sees an empty site as having no value.
What you should do is build links from other high quality and on-topic sites to your new domain. Just one high value link does wonders. A few moderate value links does more for your site than you can imagine. Make sure that these links are made in a natural way, that is, in a way that any webmaster would create a link.
There is no substitute for real work. Google appreciates and rewards it.
