It is technically possible. I have actually yesterday seen an impressive implementation from a customer who used plugin framework to load ribbon pages, pagecontrol pages from a plugin. To implement this takes effort though. You'll need to implement methods in the custom plugin interface that control the creation of pagecontrol page and construct its content. Sadly, at this point, we have ourselves not ready to use or sample code for this. If we can find some time in the future, we'll consider putting together a sample.
