As mini-jumbo already said, not very sensible.
However, there is training going on or, as in some case, training to commence, for a one-engine approach to apron and gate.
This is also in my company a discussed issue and there are cost saving reasons behind it.
Saving 2€ on fuel for each arrival (just a guess) on a fleet of more than 100 aircraft following this at least 4 times a day gives a saving of 365000€ a year.....
In case of lo-co airlines, having the #1 dead arriving at the gate allows for immediate deployment of the airstairs (B737NG) and saves about 18,5 seconds on turn-around.....
MOL will love it....
