Firstly,I do not clear what you want? Multiple choice or single choice？Arrange data sources vertically or horizontally？
But in general, merging fields is difficult to achieve based on your current code.
I think you should change the direction,for example:
1.make a viewmodel which contains two fields.
2.populate this viewmodel with the data set of these two fields
...and so on
