Interbroker statistical arbitrage possible with MT API ?

A few days ago I started playing with this idea. Imagine you have accounts open with two brokers. They don't have the same quotations. Suppose that in market rallies quotations start diverging a lot - let's say over 10 pips. Now one broker won't have the quotations 10 pips over the other. The difference should balance. So trades like:
EURUSD t0
Broker 1: 1,1950/52 LONG
Broker 2: 1,1960/62 SHORT
to
EURUSD t1
Broker 1: 1,1980/82 CLOSE +28 pips
Broker 2: 1,1970/72 CLOSE -12 pips

could be possible:

The program using the API will monitor the distance from the average and will enter opposite trades when it starts diverging over a predefined value. Should work, no ?
