Spot channels convert to rgb mode

[Ahkc]

Hello everyone, I want to convert the document containing spot channels to RGB mode. I need a script for this.

Is »Merge Spot Channels« good enough? 

»I need a script for this.«

So what is the problem?

var doc = app.activeDocument;
MergeSpotChannels();
function MergeSpotChannels(){
    var spotChannels = [];
    for(var channelIndex = 0; channelIndex<doc.channels.length;channelIndex++){
        if(doc.channels[channelIndex].kind == ChannelType.SPOTCOLOR){
            spotChannels.push(doc.channels[channelIndex]);
        }
    }
    doc.activeChannels = spotChannels;
    executeAction( charIDToTypeID('MSpt'), undefined, DialogModes.NO );
};

This script works on documents containing Rgb + Spot channels. I just need a script that converts documents containing spot channels to rgb.  my english is not good I'm sorry :))

Please elaborate on the images you are talking about? 

Are they Multichannel, CMYK, …?

Multichannel

You could add three new channels, move them to the top of the list and convert the image to RGB at the beginning of the Script.
