What characters are worth trying to get now to replace which character on my team?

this is my current team. what characters that are available in the summons should i attempt to get now to replace which character on my team?

So for this team specifically, the only character really worth it is getting SP LF SSJ2 Gohan Red to replace SSJ Kid Goku. That being said if you get SP Gohan Green from the current UST 14 banner or even SP Otherworld SSJ Goku (not sure which banners he is in) then they can replace SSJ Kid Goku as well, just not sure if it is worth it spending that many CC To get Gohan even if he would make your team better.
Also if you get SP Otherworld SSJ Goku Yellow, EX Youth Gohan Red, or SP SSJ Gohan Blue make sure you add them to your bench as they are Son Family tag boosters
