If i understood your question correctly you would like to have the ability of generating the map against Sense data at run time. The map would have to be created by means of an extension but yes it would be possible, however not trivial.
In the soon to be released Idevio Maps for Qlik Sense you can load a floor plan in your own coordinate system and use that as a background as long as the coordinates you want to display are in the same coordinate system.
