Mostly no. A hardwired restriction is that a view has a rigidly
defined list of columns with defined types. You can skirt that
restriction a couple of ways -- for example your view could be a
single column text (or xml, or hstore) with the columns you want
encoded into it.

nope -- in fact the point of views is to create a well defined
representation of something which is the opposite of what you are
trying to do.
