Welcome aboard Sim99, the short answer: no.
The first question is, why is it important that the home page be the top ranking one?
"I want them to enter through the home page" is not really the correct answer. This internal page obviously ranks higher for a reason, it's content is more relevant to the keywords.
This aligns with the concept that web sites don't rank in SERPS, web pages do. You are far better off have 10 or 12 internal pages ranking within the first two or three pages of results than having just the home page #1.
The logic: if the internal page is one that converts to a sale or membership (or whatever,) why would you want to get in the way of that? "We can't allow you to use the drive up window. You must enter through the front door or you can't buy." Fine, I'll stay in my car. :-)
Even if you did have the main page ranking #1, it would now be "in competition" with the current #1 page.
The way you would get the home page to rank instead is to optimize that page for the keyword set with more content on the page containing the keywords.
