It is possible to reduce the fullness of the ala or to adjust its shape. However, this requires additional scars which may be visible.
In general, especially when it comes to the nostrils, "Less is More." Every procedure and manuever has its risks. The risks of operating on the nostrils are asymmetry, irregularities and visible obvious scars. A surgeon has to decide if they think the small benefit of the changes to the nostril outweigh these potential risks. it sounds like your surgeon feels that the risks don't outweigh the small benefit. If he/she felt that it would really improve the result, they would probably do it.
Improving the tip will go a long way. This will make the most difference in the appearance.
If you're still not sure, request a follow up consultation to discuss this in more detail. Your surgeon should be able to explain exactly why they don't recommend it.
