Counter-Charge combat maneuver
You can attempt to interrupt an opponent's charge with a charge of your own. Your counter-charge must be a readied action against the target of your charge, and your movement path intersect the target's intended movement path within at least one square.
The unhindered movement of the target is played out as normal, up to the last square of uncontested movement (i.e. the final square it can occupy before your paths would cross). Make a Combat Maneuver check against your target's CMD.
If your Combat Maneuver check is successful, the target ends his movement immediately at his last uncontested square, and you can either make your single melee attack as part of your charge against the target, or do anything else (such as a bull rush) permitted in place of that melee attack. You also end your movement in the contested square.
If your Combat Maneuver check fails, your movement ends at your last uncontested square, your opponent gains an attack of opportunity against you, and has the option of also turning his single melee charge attack on you rather than his intended target (assuming you weren't it).
If this is a decent combat maneuver idea, then we can expect improvement feats to go along with it, such as Improved Counter-Charge, Greater Counter-Charge, and so on. Perhaps there is also a niche for a feat that would let you, after a successful counter-charge, continue your movement up to the maximum range allowed for your charge, provided the next square of your movement path is unoccupied or otherwise blocked.
This isn't really a new combat maneuver.
It seems like all you are doing is Readying a Charge and combining that with Stand Still.
Readying a (Partial) Charge is already done via Rhino Charge from the Sargava Companion.
I guess it would be worth a Feat to use Stand Still as it's own attack (not AoO) but I would phrase it as using existing mechanics for Stand Still, not as a new maneuver.
I would just say you can Ready Stand Still in place of any attack you could ready, whether a Readied Charge or regular Attack action, etc...
Already you can combine Lunge with a Readied Attack against somebody approaching you, so if you Trip them, they won't be able to close and attack you (if you both normally have equal reach, but they don't have Lunge), and you can also use that same approach with a Rhino Charge Readied (Partial) Charge.
