Rerouting on missing route?

[Jaxel]

So XenForo has a lot of routes... for instance:
http://8wayrun.com/forums/
http://8wayrun.com/members/jaxel.1/

What I want to do is... if someone types in:
http://yokappa.tv/missingroute/

Instead of displaying a 404, I would like XF to display the contents of:
http://yokappa.tv/channel/missingroute/

How would this be possible? I thought it would be as simple as adding /channel as the index route; but it appears the XF index routing system does not handle link parameters.

See the source for my vanity names addon, I do something pretty much like this

I'm using @xfrocks BD Widget Framework to handle my desired content for 404 pages.

Thanks, i did it was follows... was very easy:

<?php

class EWRcanal_Listener_Front
{
    public static function dispatch(XenForo_FrontController $fc, XenForo_RouteMatch &$routeMatch)
    {
        if ($routeMatch->getAction() == 'ErrorNotFound')
        {
            $request = $fc->getRequest()->getRequestUri();
            $splits = explode('/', $request);
           
            if (!empty($splits[1]))
            {
                $model = XenForo_Model::create('EWRcanal_Model_Channels');
                $channel = $model->getChannel($splits[1], 'slug');
               
                $fc->getRequest()->setRequestUri('/channel'.$request);
                $routeMatch = $fc->route();
            }
        }
    }
}
