Hi David,
yes, for sure. I have written a blog post about Cross-Platform Transportable 
Database some time ago, but Cross-Platform Transportable Tablespaces are
supported now by SAP as well:

Yes (theoretical and from a technical point of view), with a filter on the SAP 
schemas, but it is usually not that easy in SAP environments as the
amount of (manual) post processing steps depends on the kind of SAP system 
(ABAP or J2EE). The conversion procedure is also supported by BR*Tools
nowadays (advantage: automatic post processing is done to some level as well). 
Please check SAPnote #1003028 for more details about the necessary post
steps.

3.6. Importing user tablespaces into the new database
------------------------------------------------------
On completion of this action and some automatic postprocessing by the system 
(for example, running the postdbcr.sql script), the new database opens.
The copied database is now available in the SAP system for the additional 
postprocessing described in the system copy guide.
…
…
These steps are described in the guide "System Copy for SAP Systems Based on 
SAP NetWeaver ...", for example:
* You must create a corresponding OPS$-DB user (containing the tables SAPUSER) 
for the new <sid>adm OS user.
* To fill the SAPUSER tables, you must reset the DB password for the SAP DB 
owner (brconnect -f chpass -o sap<sid>).
* ...
You can also use SAPinst for postprocessing. For databases with a Java schema, 
you should use SAPinst to perform these postprocessing steps because,
depending on the release, more extensive postprocessing actions are required 
for Java systems. The prerequisite for using SAPinst is that you have
performed a preparation step in the source system. Refer to the relevant system 
copy guides for more information.
In addition, ensure that the database is stopped before SAPinst is started.

I have done that manual post processing steps once for ABAP systems, but in 
case of ABAP it is pretty well known what kind of additional settings,
users or objects are needed.
