Hi, Is there any possibility to use weights sharing (like in [#546](https://github.com/BVLC/caffe/pull/546) ), but transposed? It is used for [autoencoders](http://deeplearning.net/tutorial/dA.html) and [deconvnets](http://www.matthewzeiler.com/pubs/iccv2011/iccv2011.pdf)?
