Everything you mention should be doable.  Another thing to keep in mind is that
you can rip out various parts of what is currently in there if you don't need
them.  For example, a receive-only application can save quite a bit of space by
removing the TX stuff.  Also, if you are doing a correlator, you may want to
integrate the carrier tracking with it.  In that case, you would probably take
out the DDCs that are in there now.
