DOJO/Ajax: Dynamic Loading of Content & DOJO Upgrade - ajax

Question

In my application I am expected to show come configurations on UI. Currently appication makes a DOJO call and displays all the configs in UI. But, we are facing time out issues in case of huge configs say 5000 or more, which subsequently takes more time to load the page and application gets timed out since the default time for DOJO is around 3mins.
Solution: We are planning to make subsequent AJAX calls and display 50 rows of configurations at a time. This would mean, that after displaying 50 rows of configs, application will make another AJAX call until all the configs are loaded on the page. This will ensure that DOJO call is not getting timed out. We are planning to move forward with DOJO.xhrGet or DOJO.xhrPost which is a part of request package in DOJO 1.8.
Now, the issue here is that my application is configured with very old version of DOJO. Since, we want to include new request methods which are introduced in DOJO 1.8, what changes will be required here?
We have tried by including the request methods in DOJO.JS but we can see that it impacts other application aspects. Can you please let me know the steps required to include this new package in DOJO.JS?? For reference, please find a snippet of my DOJO.JS.
Any suggestions would be of great help. Thanks!!! :)
