I would not allow this. Mainly because I wouldn't allow people to react to their own actions. Nor would I allow what amounts to a workaround of the rules in order to react to things they can't perceive:Very easy you mean.
1. On your turn you Ready An Action
Trigger: When i yell ''GUNJA''
Action: I attack/cast a spell etc...
2. During the creature's turn preceeding your next turn, at some point you yell ''GUNJA'' and then use your Readied action as a Reaction. When the monsters turn ends, you next turn comes up and take an action again, which essentially equals to two in a row.
At first it may not look too bad, but i fear some abilities comboed by using actions back to back could give unexpected results.
"I yell out GUNJA when it becomes his turn."
"You don't know it's his turn. People don't have 'turns' inside the game, just outside."
"Well, then I don't know it's his turn...but I yell out GUNJA anyways..."
"No..not allowing you to use metagame knowledge in order to get around a rule."
