Sure you can, just put Rose as Leader and then add your best Extreme characters to the team (Hit is a great stunner, Zamasu is a healer, Broly attacks all enemies on the field once he's dokkan awakened...)

The problem is, it's not going to be a great team, you'd need more and better Extreme cards for that. On the other hand, your STR team looks pretty good, so for instance you should be able to get Gogeta's awakening medals pretty easily, and do other events with that team as well. If you don't want to spend any more stones on the SSJ4 Goku banner (PHY Goku Black is featured there, and he link great with Rose), you can wait for the new banners - they'll be here soon! - and hopefully you'll be able to summon some great Extreme cards.
