The Evolution of the Rondo, should I expand it out further?

This is something that I have noticed as I listen to pieces from the Early Classical to Romantic Eras, this rondo expansion until the major sections themselves get divided into 2 subsections.

Some other composer told me that I should make a new expansion and start a new phase of rondos to come like Mozart, Beethoven, and Brahms before me. But, how? Adding a second development? Beethoven already did that to Sonata Form, with one of his symphonies(can't remember if it was his eighth or seventh) having a true second development and second recapitulation in one of its movements and the preceding symphonies of his just had an extensive development section-like coda. A second coda? Again, there have been pieces by composers before me that have 2 codas. Making the C section just more contrasting material and thus making the exposition a 5 part exposition? There have been such rondos I think that are in the form of ABACADABACACoda or something similar. A 7 part exposition of ABACABA? That's pushing the development way back. Point is, I don't see much that I could do that either hasn't already been done to a certain musical form(the 2 development sonata form in one of Beethoven's symphonies for example) or that push the boundaries too far for it to be considered Rondo in any sense of the word. I tend to stick to the Mid Classical-Early Romantic Era for my rondos.
