Lin+ Asik for Rondo+ filler?

I just love the idea of having rondo on the rockets. He is not a big scorer, he is a really good rebounder, peremeter defender and ball handler who can dish out to our shooters and howard. This gives the ability for harden to play more like he did in okc. With russ at pg.i feel like this is the move tht brings rockets into top 3 seed and over portland in west.
Boston would do this, because it would be a great way to start a rebuild. If we add a first or two why would they say no?
