Pulling in Ektron search results in Episerver via Find

Hello

I'm using the latest version of Find (13.0.1)  and we will soon begin  migrate off Ektron and into EPi 

Our existing Ektron site has been indexed in Find, and we are using it as our search engine for now.  

We have our new episerver intance being indexed into the same index as our Ektron content.

I can't seem to find a way to pull our ektron pages into our new epi search results page. 

I thought I could use unified search, but it is only pulling in content from the Epi side of the index. 

I'm just using a really basic controler that doesn't have any filters applied at this time:

  var viewModel = new SearchPageViewModel(currentPage, q);
            if (!string.IsNullOrWhiteSpace(q))
            {
                var unifiedSearch = SearchClient.Instance.UnifiedSearchFor(q);
                viewModel.SearchResults = unifiedSearch.GetResult();
            }
            return View(viewModel);

Any suggestions as to how I can pull in these search results so we don't loose functionality as we move sites over to Epi?
