Converting HP70900B to HP Receiver

I have a series 70000 spectrum analyzer that I want to convert to the HP71910A.  I don't know if it can be done. 

I want to buy a broadband IF module HP70911A and replace the existing IF modules HP 70902A and 70903A.  Depending where it can be bought the 70911A can give up to 100 MHz RBW or even 300 MHz if you know how to convert it.  This would be desirable for me because I can then send the 321.4 IF signal into the QS1R SDR and get a panaramic display of the entire IF BW down to 0.1 Hz resolution. 

The QS1R is equiped with the capacity to handle dc input to 300 MHz in real time oversampling.  However something is missing.  Is the HP70911A fundamentally different from the HP70900B?  What are these model numbers?  Code words?  The 70911A is a receiver and 70900B is an SA.  So 11A means receiver and 00B means SA and you can't convert one to the other?  I saw an "HP70911A" for sale on eBay and it had the same slots that my SA has except for the broadband IF we are discussing here.  So not material differece?

In sum, just would like to know if by adding the 70911A IF to the 70900B SA will I get a broad band receiver such as the 71910A?  Or am I missing something?

Thank you for your help.
