Conversion of Hiro 3 Dagon Clothing for Modern Male Figures?

A long while ago, I had some art pieces that used H3, H3 Poses and the Dagon outfit. I would like to update some of these images to G3 or G8 but am not sure how to go about getting that original outfit to work on the newer figures. Nothing fits the characters like that outfit.
Does anyone have any suggestions?
Thanks

There are 2 products in the store which will give you clones to autofit H3 content to newer figures:
https://www.daz3d.com/a3-and-h3-shapes-for-genesis ==> fit from A3/H3 to Genesis 1.
https://www.daz3d.com/wear-them-all-autofit-clones-expansion-for-genesis-3-male-s-and-genesis-3-female-s ==> fit from H3 (and various other figures) to G3F/M

I love you!
I actually have the second one you mentioned. I forgot I had it.
