Display Document Set Columns Within The Document Set

Question

Hello all! Hopefully you all can let me know if the idea I have in my head is possible:
Background: I have a Document Library with a custom made Document Set that has about 15 columns. The way I initially designed this, I left about 10 of the fields as "Hidden" because we didn't want the user to fill out that information
when creating a Document Set. That information would be completed in the next step through a Workflow. The Document Set Welcome Page has been left pretty much untouched with the usual web parts for Document Set Properties and the view of the items within the
Document Set.
Question: What I would like to know is...would it be possible to display those Document Set fields within the Document Set itself? At the moment, if I try to add another Document Library web part and view it, the information web part is
empty, or it contains information about one of the items within the Document Set.
Simplified Structure of Document Set:
Name (required)
Fiscal Year (Required)
Total Cost (Required)
Approval Date (Hidden)
Requisition # (Hidden)
Team Members (Hidden)
Reminder Date (Hidden)
User creates a new Document Set, fills out the information, and saves (this triggers a background workflow that approves the Document Set). After approval, a new workflow is started to provide the information for the Hidden fields (and also schedules a reminder
for that Reminder date.)
The goal would be to display those Hidden fields in another web part on the page. Right now, I have users going back up to the main level of the Document Library to look at a view that contains those fields.
Hopefully I haven't confused you all too much! Please let me know if my idea is possible and any resources you might have!
Thanks!

Here is the approach to read document set columns and assign to other webparts:
for each document set you can find the id when you clicking on the document set or navigating to the welcome page,
using this id read query string and  the associated item column values and assign to otherwebpart .
Reference code:
//page_load for other webpart read the query string of welcome page
if (Page.Request.QueryString["ID"] != null)
                ID = Convert.ToInt32(Page.Request.QueryString["ID"]);
                if (itemID > 0)
                    GetDocumentSetItem(ID , site);
  protected void GetDocumentSetItem(int itemid, SPSite sSiteUrl)
            SPSite site = sSiteUrl;
            SPWeb web = site.OpenWeb();
            SPList list = web.Lists.TryGetList("DocumentlibraryName"); //where documentset content type attached
            SPListItemCollection items = list.GetItems();
            SPListItem item = null;
            if (itemid > 0)
                item = list.Items.GetItemById(itemID);//getting the current item
   //read the document set item column values and assign it other webpart controls , 
                txtDocsetidname.Text = Convert.ToString(item["FileLeafRef"]);
                txtDocsetid.Text = Convert.ToString(item["hiddenfield"]);
In the welcome page I have placed button to load webpart ,while loading the webpart I am reading the query string assigning the values to otherwebparts.
