All sights can be made traditional if you're meaning POI is at the top of the front sight blade, even the Sigs. Changing the POI (Point Of Impact) in relation to your POA (Point Of Aim) is usually done at the rear sight as it makes the most dramatic change. To "raise" your POI, you raise the rear sight. This is done by getting a "taller" sight. Conversely, if you want to lower your POI, you lower the rear sight by getting a shorter sight. Now, if you're wanting to make your POI changes at the front sight, "you do the opposite" of the rear. If you want to raise your POI, your get a shorter front sight. If wanting to lower your POI with the front sight, get a taller one.
You didn't mention the caliber of your Elite but 9mm Sigs usually have sights numbered 8 in the front and rear. If it's a .40S&W, they usually have an 8 rear and a 6 front. Now Sig does things a little differently to make it easier for people to know what sight heights they need. This is for Sig sights only. Their rule is that if you want to raise your POI, numbers up. If wanting to lower you POI, numbers down. This applies to front AND rear sights. How they do this; Sig's rear sights increase in height as the numbers increase and their front sights decrease in height as the numbers go up.
If wanting to use sights made by another manufacture, you will need to know the actual physical heights of your front and rear sights and the change in POI you want to achieve and the distance you were shooting. From this, a manufacture should be able to figure out what you need based on the data you give. Your wanting a gun that shoots POA/POI at the top of the front blade should not be hard to accomplish with the many sights available.
