you could actually turn the conforming clothes into dynamic clothing!!! by loading the individual cloth parts one by one!! and exporting them as Obj. or 3Ds. files, then if you are adventurous you could take the oBj. into a modeling program,add the extensions to the shirt and coat!!  then bring it back into poser,take it to the cloth room and make it dynamic!!! might work!!!!!!!

i should point out that even with all these adjustments(if you make them) you would not be able to re-distribute the new object(dynamic)
