There are some LF2 mods which have the this feature to do team move. I know 3 of them:
BXLF2
Robotical LF2 (only firen and freeze)
Advanced LF2
I think i have not check them dat files about team move,the possible technique that they have been used is this:
char1 do that move via D^A, char2 do it via D^A too. When char1 goes to D^A frames, he has a special bdy which interact with an ik8 of char2 and a ik8 which interact with bdy of char2. This char2 has these bdy and itr in his D^A frames. D^A frames should end with next: 999, but when there is the special char dvx: leads to a certain frame which is the "special move".
Monster which protect the character.

You have to put an ik9 or maybe something else to frame monster, so he will protect you char. The problem might be that the monster will be appeared in the same place with char, but this can be solved easily by changing centerx of monster. Also don't forget to put an special bdy in all of char frames, or at least in all frames that you want to keep it. There might be timers in study example, the thing that you should know is to make dvx: to send monster to the next frame like a circle. and in the moment that char falls in the bg, monster can be disappeared by next: 1000, which should be in all of his frames.
