If what you need can boil down to a search using the datamodel command, then it will run just fine in Sideview Utils.
http://docs.splunk.com/Documentation/Splunk/6.0/SearchReference/Datamodel
Under the hood datamodels are implemented using the search language - generally tstats, stats or transaction, and I always just use those bits and pieces directly instead of trying to get datamodel to compose them for me. If you get a comfort level with that lower layer, then again you're just running searches and Sideview Utils runs fine...
If you want to use or embed Splunk's Pivot User Interface somehow in your Sideview Utils views, that's another story entirely and that's really not possible.
