What would it take to refit Columbus+Kibo for Ariane5/Proton

"The post I made referred to the MPLM and what will become of them when the shuttle retired and the possible use of the Delta 4HLV. And the recertification process was brought up. "<br /><br />The MPLMs were to be retrofitted (e.g., add additional shielding) so that they could be left on orbit as additional modules, but I am pretty sure that has been dropped at this point due to budget issues.
