Right click on the groups and 'explode' them, then select all and right click, 'Intersect Faces' >> 'With Selection'.
If you don't want them all welded together, make new groups with 1, 2, 3, etc.. groups first then edit that group by double clicking it, do your explodes and then click out of the new group to move on.
You will end up with internal faces, but that's another story...

Or it may be that you just want all those groups to move around as one, if so simply select all and make group.
Yes, both these methods seem to have worked well, thanks!
