[TYPO3-mvc] How to implement a selectfield/SPLobjectArray containing different object types?

as I wrote I don't need single table inheritance ATM. I was thinking 
about using a field with the TCA configuration:

'contentElements' => array(
   #...
   'config' => array(
     'type' => 'group',
     'internal_type' => 'db',
     'allowed' => 'table1,table2,table3'
     'MM' => 'tx_myExt_contentelements_mm',
   ),
)

So one single TCEform field that's storing references to various other 
tables (just like the "insert Records" CE does in Typo3 v4). Each of the 
relations is storing the ID as well as the tablename, so for extbase it 
would be possible to determin the correct model to map the record on. I 
already started digging into the dataMapper stuff and found out that 
'group' fields are not supported yet natively (but you can fool extbase 
by placing a 'foreign_table' definition in TCA, as long as you only 
refer to one table in the group field).
But in general I think this would be possible to achieve quite easily if 
one knows where to start tweaking.

Thanks, I'll have a look.
