Why on earth would you include every single 6 star you have, if you haven't put iso into them at all, you probably don't use them, so why are they even a consideration?
Looking solely at your ranked up champs
Spidey supreme, hulkling, and torch are all worth it... and you don't have to burn all the gold, iso and resources to rank someone up to r3 just to then take them to r4
I would try to avoid champs that are in the 7 star pool, because that is an R4 straight out of the box

best options imo but you should rank up the one you like the most
