Wut?
I didn't quite understand your question, but here goes nothing.
The sealing process of the bijuu into Gedo Mazo takes around 3 days with a bunch of Akatsuki members helping. Plus, the host most probably has to be unconscious, to not create any interference.
You can't just seal a bijuu into Gedo Mazo in an instant.
Otherwise Tobi would have just used his S/T techs to get near one, summon Gedo Mazo and get over with it.
Instead of putting months of effort into getting the Akatsuki members to beat the jinchuuriki into an inch of their lives and then stand around the statue for 3 days in order to extract the bijuu and reseal them into Gedo Mazo. :shrug:
