Yes it is... But it also may be achievable :
see on git.biblibre.com
wip/remove_items_from_marcxml branch

It is rebased on master.
It is experimental. So if you want to test, test out of production. And
since the script which removes items from marcxml biblios is not really
optimized, consider adding biblios with bulkmarcimport rather than
upgrading.

Benefit is : that circulation and display of biblios is really quick.
(If you have many items on one biblio)

Cons : indexing is much slowed down because of Items2Marc done each time.
I saw it as a first step to usage of dom for items.

Hope that helps.
